Thanks for the idea, and info on the book. Like you said, there may be 20 percent cheese recipes without rennet.First off, this is the book. I encourage you to order a copy if you want to try making cheese.
I do eat a variety of store purchased cheese. It has to be from cows' milk. Any other milk, like goat, sheep, or whatever other milk there may be,,, wont go down.
In making cheese,, rennet to me is similar to caffeinated tea for you.
