What each ingredient does

Milk
Provides the proteins that coagulate into curds when heated and acidified.
Mustard seed
Adds pungent flavor to the whey and helps the milk separate into curds and whey.

The step that matters

Boiling until the milk coagulates. Boiling too briefly leaves the milk from separating into curds and whey, while boiling too long can make the curds tough and rubbery. Watch for clear, separated whey.
