Add the water and sugar to a saucepan just large enough to fit all the figs. Turn the heat to medium-high and stir until the sugar dissolves. Add the spices and simmer for 10 minutes.
Use any spice combination you like. Cinnamon, clove, ginger, cardamom, freshly grated nutmeg, allspice berries, vanilla bean, black peppercorns are all good suggestions. The spices in the simple syrup are subtly blended and not an overpowering taste experience.
I realize not everyone likes yogurt, so substitute the yogurt with 2 cups (500 ml) whole milk. and continue as directed. Any ratio of yogurt, to heavy cream, to half and half, to milk will work if you use the specified amount of gelatin for 3 cups (750 ml) of dairy.
