Ingredients

Directions

Prepare

  1. Cut the fat into small dice and place it in an iron saucepan with plenty of cold water.

  2. Boil until the liquid is transparent with only small scraps of brown floating, about 1.5 hours.

  3. Be cautious of splattering fat as it reaches high temperatures.

Strain

  1. Let it cool before straining into a basin through a fine strainer or wire sieve.

What each ingredient does

Beef or mutton fat
Supplies the fat that is melted and separated from water and solids to become clarified fat.

The step that matters

Boiling until the liquid turns transparent. Water must fully evaporate and the solids must brown and settle so the fat is pure. Stopping early leaves water and residue that spoil the fat, while high heat can cause dangerous splattering.
