I attempted to make yogurt yesterday. I mixed a store-bought yogurt with hot milk, reconstituted from nonfat powder.
After three hours of “incubation,” I had a very thick mixture with watery stuff on top. I stuck it in the fridge.
This morning, I tasted it and it was the most painfully sour yogurt I had ever tasted in my life. I stirred in some fructose and it ended up tasting only a little better.
How do you know when your homemade yogurt is a success, and how do you know when it’s stuff that shouldn’t be consumed? I threw mine out because it was icky, but I actually don’t know if it was “bad.”
