Interesting! I never considered using my crockpot. I actually made my first batch of homemade yogurt yesterday, and this is the method I used. It turned out very well and was nice and thick. I think adding the 1/2 cup of powdered milk makes a big difference when it comes to getting the yogurt to be thick rather than runny. :thumb:
1 quart non-fat milk. (You can use 2% too)
1/2 cup powdered non-fat milk
2 tablespoons plain yogurt with active cultures
Thermometer (glass candy thermometer works well)
Mix the milk and powdered milk thoroughly in a sauce pan.
Heat until 180 degrees, stirring frequently.
Remove from heat.
Let temperature drop to 115 degrees. This took about 45 minutes or so.
Add the 2 tablespoons of active plain yogurt. Stir well.
Temperature must be in the 115-degree range for a minimum of 4 hours. This can be achieved by setting the pan on a heating pad or various other methods. I started out using the warming area on my ceramic-top stove, but that kept the temps too high, in the 120-degree range, so I broke out the heating pad and used that instead. I checked the temps every 10 minutes or so and adjusted the heating pad levels as needed.
The longer you allow the yogurt to cultivate, the more tart it will be. I don't like mine very tart, so I stopped at 5 hours.
This batch made a little more than 4 cups of plain yogurt. I put it in 4 individual glass bowls with lids and refrigerated them.
When ready to eat, I added about a tablespoon of sugar and raspberries to mine. You can individualize it however you wish.
Also, this plain yogurt can easily be made into cheese by using cheesecloth in a colander and letting the whey drain out. Add herbs or use plain as a cream cheese substitute.
