While not cheese, exactly, homemade yogurt is delicious, easy and healthy. DO try this at home.

Heat milk to 110º F. Any milk will do—raw, pasteurized, skim, whole, or reconstituted dry milk. Per quart of milk, blend in 2 tablespoons of your favorite plain yogurt with “live cultures,” or 1/8 teaspoon of yogurt starter culture powder. Incubate the milk plus culture at 100-110 F for 8 to 12 hours or longer if you like. Do not jiggle. When the acid level reaches pH 5.2-pH 4.8 or so, the milk will thicken up. Done!
