Pan for Boiling Milk

Ingredients

Directions

Prepare

  1. Fit a pan holding the milk to a boiler with a pipe leading to a cold water reservoir to regulate steam.

  2. Strain the milk and stir it constantly and briskly.

Reduce the milk

  1. When the water boils, reduce the heat and close the furnace door to maintain a moderate boil.

  2. After two hours, the milk should reduce to about 12 pints.

  3. About 15 minutes before finishing, dilute the egg yolks with 1 pint of milk and gradually stir it into the mixture.

Finish and bottle

  1. Once done, strain the milk to remove the egg yolks and cool it in tureens while stirring to prevent a film from forming.

  2. Bottle the milk, cork it, and boil for 15 minutes.

What each ingredient does

Milk
Forms the body of the condensed product; reducing it by boiling concentrates the milk solids and sugars.
Egg yolks
Add richness and thickening as they set gently into the reduced milk.

The step that matters

Adding the egg yolks. Yolks can scramble if they meet very hot milk directly. Diluting them with some milk first and stirring gradually tempers them, so they blend in smoothly instead of curdling.
