What each ingredient does

Milk
Its proteins set into curds when acidified, leaving the watery whey behind.
Prepared mustard
Its acidity causes the milk proteins to curdle and separate from the whey.

The step that matters

Add prepared mustard and stir well. The mustard's acid must be evenly mixed into the hot milk so the proteins curdle throughout. Uneven stirring leaves patches of unset milk, so the curds and whey separate poorly when strained.
