Hey guys, I want to make cheese this morning for the very first time (mozzarella). I'm looking at the bottle of super industrial strength animal rennet I bought and it says I should dilute it with cold boiled water. 1) How much water? I want to make half a pound, so it seems like I should use two drops. How much water is needed for two drops? 2) By cold boiled, do they mean I should boil the water and then let it get cold? Thanks!
