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 ↓
Sorrel Sauce
Ingredients
Directions
Prepare the sorrel
Pick and wash the sorrel.
Place the sorrel in a saucepan with a little water and stir to prevent burning.
When tender, drain the sorrel and finely mince it.
Make the sauce
Fry the minced sorrel in a saucepan with a little butter for 30 minutes.
Dredge the mixture in 1 tablespoon of flour and moisten with boiling cream.
Let it stew on low heat for 1 hour.
Add a little coarse sea salt and sugar if too acidic.
Before serving, thicken with the beaten yolks of 4 eggs.

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
- Provides the sour, tangy flavour that defines the sauce.
- Butter
- Adds richness and carries flavour while the sorrel fries.
- Flour
- Coats the sorrel and helps thicken the sauce as it cooks.
- Boiling cream
- Moistens the mixture and gives the sauce a smooth, rich body.
- Egg yolks
- Thicken the sauce and add richness when beaten in before serving.
- Sugar
- Balances sourness from the sorrel, added only if the sauce is too acidic.
The step that matters
Adding the beaten egg yolks. Egg yolks thicken by setting when gently heated. If the sauce is too hot when they go in, they can scramble and turn grainy. Add them off the heat or over low heat, stirring constantly, and only just before serving.
Swap the sorrel
How well each one fits the dish's main ingredients (butter, flour, cream, sugar, egg):
- Nutmegfits about as well
- Sorrelthe original
- Cinnamonfits about as well
- Capersfits less well
Fit is the average pairing score against butter, flour, cream, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
