Homemade Yogurt

Step 5 Now you have yogurt!

Ok, now you should have yogurt! Put it in the fridge to stop the fermentation process and help it firm up. If you have a lot of yellowish liquid floating around, don't worry, this is whey. You can stir it back in or, if you're going to strain your yogurt, just leave it.
If you think you might make another batch, save about 1/2 a cup for the next time instead of using a store-bought yogurt.
