  3. Place the milk in a double boiler and heat until steaming.

  4. Watch carefully until the milk separates in the double boiler or crock.

What each ingredient does

Clabbered milk
Its acidity has already thickened the milk, and the curds form from its proteins as it heats.

The step that matters

Heating the milk gently and watching for separation. Milk proteins coagulate into curds when heated gently; overheating makes the curds tough and grainy, so the milk should be heated slowly and removed once it separates.
