Why it works: Sorrel and flour match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 231 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Common Sorrel Sauce
Ingredients
Directions
Prepare the sorrel
Wash the sorrel thoroughly and place it in a well-tinned or enamelled saucepan without water.
Add the butter, pepper, and salt, then stew gently while stirring until very tender to avoid burning.
Drain the sorrel on a sieve or press out the liquid, then chop it finely.
Finish the sauce
Boil the chopped sorrel again for a few minutes with gravy, cream, or milk mixed with flour, or just with a fresh slice of butter.
Stir in the beaten egg yolks just before removing from heat for a creamier sauce.
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, lemony acidity that defines the sauce's flavor.
- Butter
- Adds fat and richness, giving the sauce a smooth, rounded mouthfeel.
- Gravy, cream, or milk
- Adds liquid and body, loosening the chopped sorrel into a sauce.
- Flour
- Thickens the liquid so the sauce holds together rather than running thin.
- Egg yolks
- Enriches and thickens the sauce, adding a creamy texture when stirred in off the heat.
The step that matters
Stew the sorrel gently without water. Sorrel contains a lot of water and can scorch on the bottom of the pan before it softens. Low heat and constant stirring let it collapse in its own moisture. Stirred-in egg yolks can scramble if the sauce is too hot, so they go in just before removing from heat.
Swap the sorrel
How well each one fits the dish's main ingredients (butter, pepper, cream, flour, egg, sugar):
- Nutmegfits better
- Sorrelthe original
- Cinnamonfits about as well
- 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.
