I have been thinking about making my own yogurt for some time now and I've been looking for a really easy recipe.
Don't get me wrong, I don't know that recipes get easier than yogurt, but many require thermometers and whatnot, and I wanted something with no equipment required.
I found a method in which one can make yogurt in a crockpot!
I found it at A Year of Crockpotting and you can see it below.
Ingredients/Supplies:
- 8 cups (half-gallon) of whole milk
 - 1/2 cup store-bought natural, live/active culture plain yogurt
 - thick bath towel
 - crockpot
 
- Plug in your crockpot and turn to low.
 - Add an entire half gallon of milk.
 - Cover and cook on low for 2 1/2 hours.
 - Unplug your crockpot.
 - Leave the cover on, and let it sit for 3 hours.
 - When 3 hours have passed, scoop out 2 cups of the warmish milk and put it in a bowl. Whisk in 1/2 cup of store-bought live/active culture yogurt. Then dump the bowl contents back into the crockpot. Stir to combine.
 - Put the lid back on your crockpot. Keep it unplugged, and wrap a heavy bath towel all the way around the crock for insulation.Go to bed, or let it sit for 8 hours.
 - In the morning, the yogurt will have thickened---it's not as thick as store-bought yogurt, but has the consistency of low-fat plain yogurt.
 - Blend in batches with your favorite fruit.
 
Save 1/2 cup as a starter to make a new batch.
