Koumiss

Ingredients

Directions

The book gives no oven temperature. The 140°F in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Heat the milk to 140°F-150°F (60°C-65°C).

  2. Add the essence of pepsin and stir to mix.

Coagulate and finish

  1. Let it sit in a warm place until coagulation occurs.

  2. Beat the curd until it is finely divided.

What each ingredient does

Cow's milk
Its milk proteins form the curd that gives kumis its body and texture.
Fairchild's essence of pepsin
This enzyme clots the milk proteins, turning the milk into a soft curd.

The step that matters

Heat the milk to 140°F-150°F (60°C-65°C). Pepsin works best at warm temperatures. If the milk is too cool, clotting is slow; if it is too hot, the enzyme can be weakened or destroyed, so the curd may not form properly.
