Three Terrapin

Ingredients

Directions

Prepare the terrapins

  1. Boil the terrapins in water for 10-15 minutes until nails come out and back skin rubs off.

  2. Transfer the terrapins to fresh boiling water and boil until the connecting shell cracks, about 50 minutes.

  3. Remove gall and sandbags, then cut up the terrapins, saving all the juice.

  4. If not tender, place the terrapin pieces in a pan with a little butter and stew.

Make the sauce

  1. Mash the yolks of the hard‑boiled eggs with 2 tablespoons of flour.

  2. Add a little terrapin water or cream to the egg‑flour mixture to make it smooth.

  3. Heat ¼ teaspoon of mace and ½ cup of cream in a saucepan.

  4. Add ½ pound of butter to the saucepan.

  5. Stir in the egg‑flour mixture and let it boil once.

  6. When the sauce thickens, add 1½ cups of wine.

Serve

  1. Pour the sauce over the terrapin and serve.

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

What each ingredient does

Hard-boiled eggs
Their yolks, mashed with flour, thicken the sauce and give it a rich body.
Flour
Combined with the egg yolks, it helps thicken the sauce as it heats.
Butter
Adds richness and a smooth, silky texture to the sauce.
Cream
Adds richness and moisture, softening the sauce into a creamy texture.
Wine
Adds acidity and depth of flavour to the finished sauce.

The step that matters

Stir in the egg-flour mixture and let it boil once. Egg yolks thicken when heated, but if the sauce boils too hard or too long after the yolks go in, they can scramble and turn grainy. Add the mixture to hot liquid gradually while stirring, and bring it only to a single boil so the sauce thickens smoothly.

Swap the mace

How well each one fits the dish's main ingredients (egg, flour, cream, butter, pepper, wine):

  1. Nutmegfits better
  2. Tarragonfits better
  3. Parsleyfits better
  4. Macethe original

Fit is the average pairing score against egg, flour, cream, butter, pepper, wine. Candidates are from the same food group and used in at least 100 recipes.
