What each ingredient does

Milk
Provides the proteins that set into soft curds when rennet acts on them.
Essence of rennet
Enzyme that coagulates milk proteins, causing the milk to separate into curds and whey.

The step that matters

Let the mixture stand undisturbed in a warm place. Rennet needs gentle warmth to work; milk that is too hot can denature the enzyme, while cold milk sets slowly or not at all. Moving the bowl during setting breaks the forming curds.
