Creamy Homemade Yogurt
What happens when a novel experience turns into a regular routine? You get to eat creamy homemade yogurt as part of your regular diet. For me, making the homemade yogurt phenomenon started as a curious experiment that quickly turned into something bigger than I could imagine. Not only did I learn about fermentation and a new cooking technique, I realized that the act of making yogurt at home, has additional valuable contributions besides enjoying a delicious and nutritious snack.
It all started when I was reading about Middle Eastern cuisine and in particular, Lebanese cuisine. While reviewing Maureen Abood’s cookbook, Rose Water and Orange Blossoms, it became evident that yogurt was a central ingredient in Lebanese food. In many of her recipes homemade yogurt or labneh, cheese made from yogurt, was the central ingredient. As a result, I believed if I really wanted to understand this cuisine, then I must learn how to make its most central ingredient, yogurt.
Unfortunately, the very first batch of yogurt I made did not set properly. I reached out to Maureen Abood and she explained, sometimes the yogurt just does not set up. It happens. Discouraged, but not daunted I tried again with a different yogurt starter and had great success. What a triumph. It was like the first time I made a loaf of bread, something I thought was impossible was now possible.
My initial taste of the inaugural homemade yogurt was a revelation. This is one of those foods where you can taste the difference between homemade and store-bought. Homemade yogurt has the distinctive acidic tang, but it is a lot creamier in texture. I used to not like plain yogurt without any sweetener, but homemade yogurt has a je ne sais quoi taste about it. It is fresh, creamy, mild and tangy all at the same time. Can you taste fresh? Yes. It is the difference between eating an egg just plucked from the chicken coop to eating one bought from the store and is 4 weeks old. There is a presence that is hard to describe but you know it is there.
However, to change the habit and forgo the convenience of buying yogurt, it takes more than a curiosity to turn a novel experience into a weekly routine. After making yogurt a few times, I came to realize three benefits that will add up to significant changes for the better. First, I could support the local Hudson River Valley dairy industry, which consists mostly of family-run dairy farms that practice sustainable farming. Second, I could save money by not buying individual yogurt containers. Third, I will reduce my carbon footprint by buying locally sourced food and not buy all those plastic containers. This triple reinforcement, plus the desire to reduce the amount of sugar in our diet, sealed the deal and I started my weekly homemade yogurt routine.
Hudson River Valley Milk
Fortunately, my local grocery store carries several brands of milk that come from dairy farms in the Hudson River Valley. Most of the dairies source their milk from a cooperative of dairy farms that meet their standards of quality, sustainability, and humane treatment of animals. These brands are not USDA organic milk, but I know they are operating under the best practice policies to produce quality milk, maybe even better than the USDA standards. Another bonus is this milk is not ultra-pasteurized, which is crucial for making yogurt or any type of cheese. Even though it is not labeled USDA Organic, it is as organic as it can be.
Most of the USDA organic milk you find in the major grocery stores, is ultra-pasteurized. This is done so the milk has a longer shelf life. It is the one thing the industrial organic dairy farms must do in order for grocery stores to stock their product. This is because organic milk is more expensive and thus takes longer to sell. Unfortunately, ultra-pasteurization kills off good bacteria as well as the bad bacteria in the milk. It is the live cultures, the good bacteria, that help create yogurt and cheese, plus pasteurized milk has more nutritional value thank ultra-pasteurized.
Hudson River Valley Dairies
Listed below are dairies whose products are available in my area.
This post is not a sponsored post. I am just passing along my experience and research about local farming and how a person can make a difference to slow down climate change. I am sure there are other dairies out there that produce top quality milk and practice sustainable farming, even in my area. The dairies listed are just the ones available to me at this time.
Lower Your Carbon Footprint
I am lucky to live in an area that has a long history of family-run farms and agriculture, but it is only recently that they became available. Before I could buy local milk, I found a brand of organic milk that was not ultra-pasteurized in my local health-food store, Natural by Nature. This company is a family run business in Pennsylvania, so it is not too far away so I still consider it local. Fortunately, I did not have to look all over the county looking for it either. You might have to widen your circle, but hopefully, you can find an affordable source of organic pasteurized milk near you without too much trouble.
Over the years I have come to understand that any agricultural industry involving cattle has enormous environmental concerns from the methane gas released into the atmosphere, to the pollution from the runoff into our groundwater, and the health and safety of the cows. In my opinion, supporting local farmers who maintain environmentally friendly farming practices, and creates a healthy and humane environment for the cows, has a multiplier effect. There is less pollution compared to its industrial counterpart, creates food that is not stripped of nutrition because the cows eat an appropriate diet without growth hormones and antibiotics, and it helps local economies.
Helpful Tips for Making Homemade Yogurt
At its most basic, yogurt is milk with added live cultures, Streptococcus thermophilus, and Lactobacillus delbrueckii bulgaricus, that ferment in a warm environment until thick. It is the live cultures and warm incubating temperature that are essential to transforming milk into yogurt.
Yogurt is relatively simple to make but it does take some time for it to ferment and thicken. I found starting the process at night after dinner was the easiest way to work making yogurt into a weekly routine. This way the yogurt could incubate in the oven overnight and as soon as I woke up I placed the yogurt in the refrigerator for the second resting period. Later that afternoon or early evening, I strained out the whey for 3 hours.
The standard formula is: for every half-gallon (2 l) of milk, you need 2 tablespoons (30 ml) of yogurt starter. It is a one to one ratio: 1-quart milk to 1 TB yogurt starter. Using this ratio, the recipe easily scales up if you want to make more. Don’t be tempted to add more starter. One, you don’t need it and two, it will make the yogurt grainy.
The temperatures listed in the recipe are important for successful fermenting. Therefore, you need to pay attention and make sure the milk does not come to a boil and later, drop below 115°F when it’s time to add the starter. Also, a warm environment is essential for the cultures to do their thing. I have read, the incubation temperature is ideally at 100°F (38°C). If you have to keep it on the counter, wrap it up in a blanket and place under your kitchen cabinets or near a heating vent. If your cabinets have undermounted lights, turn them on. Room temperature is not ideal, but it might take longer for the yogurt to ferment.
I find the most reliable place to incubate the yogurt is in my oven with the oven light on. It is out-of-the-way in the oven and the yogurt stays warm from the heat of the light bulb. Because I have a tendency when something is out of sight, it is also out of mind, I place a sign on the oven door with big lettering Y O G U R T and a note of the time. Without that sign, I would completely forget about the yogurt and turn on the oven.
Not all commercial-brand yogurt are equal. Read the label and only use real yogurt with live active yogurt cultures. Stay away from brands with thickeners and stabilizers. I use Fage or Dannon, whole milk or low-fat plain yogurt with consistent results. Any good quality and real yogurt should work.
Yogurt for the Family
Would I make this if my kids were young and still living at home? Would they eat it? Maybe. Though, I would definitely need to sweeten the yogurt to get them to eat it. I found a small amount, about 1 teaspoon, of real maple syrup or honey, to a half a cup of yogurt gives a subtle sweetness and reduces the tang. Cinnamon also adds a sweet impression without the extra sugar. You can also sweeten yogurt with fresh fruit, real fruit purées or jams, and fruit compote. Even though you are adding some sugar, it is significantly less sugar than the store-bought variety. It is certainly worth a try.
An easy blueberry compote is roast 2 cups (500 ml) of fresh blueberries tossed with 2 TB of sugar in a 350°F (175°C) oven for 18 minutes. Tip the blueberries and their juices in a bowl and add 1/2 teaspoon of lemon juice and a 1/2 cup of fresh blueberries. Stir and allow to cool. This recipe comes from Yogurt Culture (linked below). It is super easy and incredibly delicious. When mixed with yogurt, it makes the best blueberry yogurt I have ever had. I am positive my children would have gobbled it right up.
Recipe Inspiration for your Homemade Yogurt
Like buttermilk, yogurt mixed with other herbs and spices is a great marinade for chicken and lamb.
My Inspiration and References
Here is a list of the three references I used over the past two years to learn about making yogurt and its history. If you want to really learn all about fermentation, the book The Art of Fermentation has everything you need to know about making all types of fermented food.
It may look daunting to make your own yogurt, but it is relatively simple. In the beginning, you need to keep an eye on the temperature, but mostly you just have to wait and give the cultures time to ferment. Other than the yogurt culture, the most important ingredients are time and temperature. You need 8-10 hours to incubate the yogurt in a warm draft-free environment, and an additional 8 hours in the refrigerator to finish. Once these steps are complete, you can eat it right away or strain out some of the whey for Greek-style yogurt.
Because there are only two ingredients in yogurt, use the best quality milk and yogurt you can buy. For best results, the yogurt used as your culture must contain real live cultures and no fillers, gums, or artificial ingredients. I use Fage and Dannon yogurt whenever I start with a new yogurt culture.
Seek out organic milk that is not ultra-pasteurized as this process kills off important and healthy bacteria needed for making yogurt.
You can use your homemade yogurt as a culture for up to 3-4 generations. After that, start over with a new batch of yogurt bought at the grocery.
This recipe scales up to 1 gallon of milk with ¼ cup (65 ml) fresh yogurt culture.
Yield: Makes about 7 cups (1 L 750 ml) yogurt before straining out the whey.
Serving size is a half a cup (125 ml)
- Heavy bottom stock pot or Dutch oven with lid
- Instant read thermometer
- Small bowl for tempering the starter
- Stainless steel mixing spoon or rubber spatula
- Large bowl partially filled with ice optional
- A warm and dry place like an oven for incubating the yogurt
- Triple layer cheesecloth or thin flour sack towel
- Storage container
- ½ gallon of milk whole or 2%, preferably organic and not ultra-pasteurized
- 2 TB yogurt with live active cultures like Dannon or Fage
Prepping your utensils
Make sure all your utensils, pots and bowls are clean. Clean them with hot water and soap and drip dry on a clean kitchen towel. I do not sterilize my utensils or pots when I make yogurt, but some people do. If you wish to sterilize your utensils and pot, run them through a complete cycle in your dishwasher. You can sterilize your instant-read thermometer by placing the probe in a mug of boiling water and drip dry on a clean kitchen towel.
Heat the milk
Rub an ice cube over the bottom and partially up the sides of your stock pot. This helps the milk from sticking to the bottom of the pot. If you do not have ice cubes, run the bottom of the pot under cold water and empty any water that collects in the pot.
Pour your milk in the stock pot and set the burner between medium / medium-high.
Take your starter, 2 tablespoons of yogurt out of the refrigerator and add it to a small bowl like a cereal bowl. Set it aside so it will come to room temperature while you heat and later cool the milk.
Slowly, heat the milk until it reaches 185°F / 85.5°C without stirring. Any temperature at or slightly above 180°F (82°C) but below 195°F (90.5°C). You do not want the milk to boil or be too hot and kill off the important yogurt-making bacteria.
When you reach 185°F / 85.5°C, lower the heat and maintain that temperature for 5 minutes.
It is hard to maintain a constant temperature, at least on my stove, just keep it in the 180°F - 186°F /82°C- 85.5°C range. If you go below 180°F (82°C) stop stirring and turn up the heat until you get back at that temperature.
Cool the milk
Turn off the heat and remove the pot from the stove. Let the milk rest until it cools down to 115°F (46°C). I allow my milk to cool on the counter and stir it every now and then to help release the steam. I set the timer to keep track of the time and check the temperature frequently. This process can take around 35 minutes, give or take.
A faster method of cooling the milk is to fill a large bowl partway with ice and cold water. The bowl needs to be large enough to accommodate your stock pot with ice water surrounding the bottom and partway up the sides of your pot. A sink will work as well. Stir the milk in a back and forth manner every now and then until it is cool. Remove the pot from the ice bath when it reaches around 118° – 120°F (48° - 49°C). Place on the counter and keep the instant-read thermometer in the milk so you do not cool the milk below 115°F (46°). If the milk does fall below 115°, place the pot back on the burner and heat it up 115°F (46°C).
Add the Yogurt Starter
Add one ladleful of the 115°F (46° C) milk in the bowl with your starter yogurt. Whisk the yogurt mixture until well incorporated then pour the yogurt culture in the pot with the milk. Stir then cover. Place the inoculated milk inside a draft-free and warm space.
Incubate the yogurt culture
Place your yogurt culture in a warm draft-free place. In my house, my oven is the best spot. Keep the oven warm by keeping the oven light on. I found it does not always work if I let the yogurt incubate on the counter. According to Cheryl Sternman Rule in her book Yogurt culture, the ideal temperature for incubating yogurt around 100°F (38°C).
Allow the cultured milk to incubate for 6 – 10 hours. Sometimes, it takes longer, up to 12 hours, but the consistent incubation time is around 8-10 hours. The yogurt is done when it looks thick and solid with some liquid, the whey, sloshing about when you jiggle the pot. It will look like plain yogurt.
One final step before eating your yogurt is to chill it in the refrigerator for several hours. Tip the yogurt in a bowl and tightly cover with plastic wrap or a tight-fitting lid. Add the yogurt to the refrigerator and chill for 6-8 hours or overnight. This extra step develops more flavor and a creamier consistency.
Voiá, you just made yogurt!
Before you use up your yogurt, measure out 2 tablespoons (30 ml) to ¼ cup (60 ml) of yogurt and place in a bowl with a tight fitting lid. Label and date the yogurt. You will use this yogurt for your next batch of yogurt. Store in the refrigerator for up to 7 days. Taste before using to make sure it is not starting to turn. You can get 3-4 generations of yogurt when using starter from homemade yogurt. After that, start fresh with a new batch of yogurt from the grocery store.
Greek Style Yogurt
Normally, I strain my yogurt for about 2-3 hours to thicken it up and produce Greek Style yogurt.
To strain the yogurt, line the bowl of a fine mesh strainer or colander with a moistened triple layer of cheesecloth or a damp tea towel. The length of the towel or cheesecloth should drape over the sides of the strainer. Place the strainer or colander over a large bowl to catch the whey.
Scrape the yogurt into the lined strainer. Draw up the four corners of your cheesecloth or towel and bring them together. Tighten them close to the yogurt and tie with a string or twisty. Place the bowl with the colander in the refrigerator and drain the yogurt until it reaches the consistency you desire. The longer it strains the thicker it gets. I like the consistency after straining for 3 hours.
When done, place the yogurt in a glass container with a tight-fitting lid and store in the refrigerator. The yogurt will keep for a week.
If your yogurt is thicker than you like, add some of the whey back in to loosen it up.
Reserve your whey and store in a covered container in the refrigerator for 2 weeks.
Yogurt dries out inconsistently throughout the incubating and straining process. This creates some lumpy spots in your yogurt. This is normal. If you want smooth yogurt, spoon out the amount you want then whisk it right before using. Whisking the yogurt will make the yogurt looser, but it gets out the lumps.
Don’t throw out the whey. It is great in many recipes and for marinades. Use whey in any recipe calling for traditional yogurt, not Greek yogurt, or milk like in baked goods, pancakes, and bread. Whey is acidic, so it will activate the baking soda. Use in smoothies. Use as a tenderizer for meats and in marinades. Whey will last in the refrigerator for up to 2 weeks.
