Common Sorrel Sauce

Ingredients

Directions

Prepare the sorrel

  1. Wash the sorrel thoroughly.

  2. Place it in a well-tinned saucepan without any water.

  3. Add a small slice of butter, salt, and pepper.

  4. Stew gently while stirring until tender.

  5. Drain the sorrel on a sieve or press out the liquid.

  6. Chop it finely.

Finish the sauce

  1. Boil the chopped sorrel again for a few minutes with gravy, cream, or milk mixed with flour, or just with more butter.

  2. Stir in beaten egg yolks just before serving to soften the sauce.

  3. Add sugar for extra flavor if desired.

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

What each ingredient does

Sorrel
Provides the sharp, acidic flavor that defines the sauce and breaks down into a soft purée when stewed.
Butter
Adds richness and a smooth, glossy mouthfeel to the sorrel.
Gravy, cream, or milk
Adds liquid and body, thickening the sauce when combined with flour.
Flour
Thickens the liquid so the sauce holds together rather than running thin.
Egg yolks
Enrich and soften the sauce, adding richness and a smoother texture when stirred in.

The step that matters

Stirring in the egg yolks. Egg yolks thicken when heated, so if the sauce is boiling when they go in, they can scramble and turn grainy. Adding them just before serving, off the boil, keeps the sauce smooth.

Swap the sorrel

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

  1. Nutmegfits better
  2. Sorrelthe original
  3. Cinnamonfits about as well
  4. Tarragonfits less well

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