Clarifying Fat

Ingredients

Directions

Prepare

  1. Cut the fat into pieces the size of a filbert and remove all skin.

  2. Place the fat in an iron pot and add ½ cup of water for every pound of fat.

Clarify

  1. Heat over a hot fire, stirring occasionally to avoid burning.

  2. When no more froth arises and the liquid is clear, remove the pot to a cooler part of the stove.

  3. Let it stand for a while and then drain through a sieve.

What each ingredient does

Fat
Is the substance being rendered; melting it separates pure fat from solids and water.

The step that matters

Removing the pot when the froth stops and the liquid is clear. The froth signals that the water is boiling off. Once the water is gone, the fat keeps heating and can scorch or brown, so the pot should move to a cooler spot at that point.
