What each ingredient does

New milk
Its proteins curdle when acid from the mustard is added, separating solids from liquid whey.
Made mustard
Its acidity causes the milk proteins to coagulate, producing the curds and clear whey.

The step that matters

Adding the mustard to the boiling milk. Stirring in the mustard while the milk is boiling makes the proteins curdle quickly and cleanly. Adding it too little or stirring poorly can leave the milk partly curdled and the whey cloudy.
