Several months ago I started making my own yogurt. We usually go through at least one large container of plain yogurt a week which costs about $2 a carton. I can make my own for less than $2 and it makes about two yogurt containers worth or 64 ounces. For simplicity sake, let's say it comes out to about $1 dollar per 32 ounces. It doesn't save much money but it's simple to make and there's just something very satisfying about making your own yogurt. It's one of those foods I always assumed you had to buy until I tried to make my own.
Here's the original recipe I used and a quick summary of how I make my yogurt. While there is little labor involved it is a long process so plan accordingly. The total process takes 13.5 hours. I like to start mine around four or five in the afternoon, so it will be ready by the morning. I think it's okay if it sits covered for more than eight hours.
Crock Pot Yogurt
- Pour 8 cups of whole milk into crockpot
- Cook on low for 3 hours
- After three hours unplug the crockpot and allow to sit for 2.5 hours
- After 2.5 hours whisk in 1/2 plain yogurt as a starter culture. I always use store bought for this, I think the bacteria is stronger in it, but homemade from your last batch may work as well.
- Cover the crockpot with a towel and allow to sit for 8 hours.
- Decant into smaller containers and refrigerate.
