I've made beer for quite a while, but I want to try making my own mustard. And/or cheese. Those seem like fun too.
Waiting on a procedure and detailed recipe for your 1 day mozzarella cheeseI have made cheese. It's rather cheep, and easy to do. I also only ever used vegetible rennet.
I recomend starting with making mozzarella untill you know what your doing. A mix up a gallon powered milk, and add a pint of heavy whipping cream, as an excellent replacement for fresh cow's milk.
Mozzarella doesn't require aging, so you get to enjoy it the same night. Most other cheeses need to be pressed, for several days to years.
I also make soap. I told my wife, it was a nice clean hobby Soap, if actaully fun to make from scratch, and like wine there's a bit of artistic expression allowed. Soap bars make excellent presents too.
