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 any water.
Add the butter, salt, and pepper.
Stew gently while stirring until very tender to prevent burning.
Drain the sorrel on a sieve or press out the liquid.
Chop the sorrel as finely as possible.
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 to soften the sauce.
Add sugar if desired.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Sorrel
- Its leaves break down into a soft purée and supply the sour, tangy flavour of the sauce.
- Butter
- Adds richness and a smooth, rounded mouthfeel to the sauce.
- Egg yolks
- Thicken and enrich the sauce, giving it a softer, creamier texture when stirred in off the heat.
- Flour
- Helps thicken the liquid added to the chopped sorrel, giving the sauce body.
The step that matters
Stir in the egg yolks off the heat. Egg yolks thicken through gentle heat and can scramble if the sauce is too hot. Removing the pan from the heat before stirring them in keeps the sauce smooth and creamy.
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.
