Mock Terrapin

Ingredients

Directions

Prepare the head

  1. Select a calf's head and have it thoroughly cleaned by a butcher.

  2. Wash and dry the head with a coarse cloth.

  3. Place it in an iron pot with cold water and a little coarse sea salt.

Cook and cool

  1. Boil gently until the meat is tender enough to pierce easily with a fork.

  2. Remove from heat and let it cool in the cooking liquid overnight.

  3. The next morning, remove the head and boil down the liquid to ½ pint.

Finish the soup

  1. Carefully cut the meat into small pieces.

  2. Place the meat back over the fire, add 2-3 tablespoons of the cooking liquid, ½ cup of cream, 1 tablespoon of butter, and pepper to taste.

Cream and pepper barely smell alike, yet cooks put them together in 21,449 recipes: they work on texture and structure more than aroma.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Calf's head
Provides the meat and gelatin that give the soup its body and rich texture.
Cream
Adds richness and a smooth, velvety mouthfeel to the finished soup.
Butter
Adds fat for flavor and a silky finish to the soup.

The step that matters

Boil gently until the meat is tender. Vigorous boiling toughens meat proteins and makes the broth cloudy, while gentle simmering lets collagen slowly break down into gelatin, yielding tender meat and a body-rich liquid.
