What each ingredient does

Milk
Provides the liquid whey and the milk proteins that curdle and separate during the process.
Made mustard
Its acidity curdles the hot milk, separating the solid curds from the clear whey.

The step that matters

Add the mustard to the boiling milk and stir well. Stirring disperses the mustard evenly through the hot milk so the proteins curdle uniformly. Uneven mixing leaves some milk uncurdled, which makes separating a clear whey harder.
