My kids can go through crazy amounts of yogurt.
I know its good for them, in theory, but store bought yogurt has its issues including preservatives and price not to mention all the packaging so I recently decided to jump on the homemade yogurt bandwagon.
If I had known how easy it was I would have done this years ago!
There are basically 4 steps to the yogurt making process...
- heat milk to about 185 degrees
- let the milk cool back down to about 100 degrees
- add a small amount of plain yogurt to your warm milk (this is like a seed of yogurt cultures... you need to have cultures to make more cultures)
- then just wait... and viola... yogurt!
Now, there's lots of variables that come into play if you do enough reading on the yogurt making process. You'll find some people prefer certain wait times and temperatures and it seems they all give similar results as long as you don't kill your yogurt cultures. Our first batch of crock-pot yogurt turned out okay... it had a good flavor and the kids ate it all but it had a curdy texture sort of like cottage cheese. Some research led me to believe it was due to a slightly higher than necessary temperature during the wait time.
I've now settled into a hybrid process. I use the crock-pot but I don't leave it sit all night as it just seems like too long. When the cultures are working to thicken the milk it seems there's a point at which its as thick as its ever going to be so leaving it longer is just not necessary.
There's plenty of good info out there already so there's no sense in me reinventing the yogurt wheel.
Here are the 2 sites I found most helpful and to the point:
My process is sort of a hybrid and works well for me. I do use the crock-pot but not overnight. I've found that setting the crock-pot to low to heat the milk, turning it off for the cool down, and then simply wrapping it in 2 thick towels is sufficient for the wait time. The temperature stays just right long enough to finish with no need to mess with turning anything off and on. I've also found that it really only takes 4-5 hours to get finished yogurt.
The kids like the thick style yogurt best so I do use cheese cloth to drain a good bit liquid out of it. This can be done overnight while it sits in the refridgerator and means you wake up to a fresh bowl of thick, cold yogurt in the morning!
I'm feeling pretty good about this. I'm even going to show you the inside of my refrigerator. Because in there is homemade yogurt right beside some of the strawberry jam I made from the strawberries in our little berry patch which just happens to be one of the kids' favorite things to add to their yogurt.
Another good thing... the liquid that is drained off the yogurt is whey (the jar behind the yogurt with the yellow-ish liquid)! It seemed wasteful to just dump it and a little research seems to indicate it can be used to replace the water in baking recipes and lots of people use it in their bread making. Whey is full of good stuff especially protein so I'm going to use it for my next batch of bread and see how it goes.
Now go make yogurt!
