After fermentation, Test your yogurt. It might be a bit thin and watery for your tastes. If this is the case, line a colander with a clean smooth
surface cloth (kitchen towel, t-shirt, muslin “jelly bag”). Cheesecloth is too porous for this use. Fasten the cloth with clothespins. Ladle the yogurt into the colander and let it sit over a collection pot for several hours. Ideally, this should be refrigerated.
If your yogurt is to your liking, put into an airtight container and store in the fridge for 1-2 weeks. If the yogurt is too thick for your tastes, take some of the liquid in the bottom of the collection container (whey) and mix it back in.
