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 it in a saucepan with a little water and stir to prevent burning.
When tender, drain and finely mince the sorrel.
Cook and season
Fry the minced sorrel in a saucepan with a little butter for 30 minutes.
Dredge the sorrel in 1 tablespoon of flour.
Moisten with boiling cream.
Let it stew on low heat for 1 hour.
Add a little coarse sea salt.
Add sugar if too acidic.
Finish and serve
Before serving, thicken with the beaten yolks of 4 eggs.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sorrel
- Provides the sour, lemony flavour that defines the sauce.
- Butter
- Adds fat for richness and a smooth mouthfeel as the sorrel fries.
- Flour
- Coats the sorrel and thickens the sauce as it cooks with the cream.
- Boiling cream
- Adds moisture and richness, producing a silky body as it stews.
- Egg yolks
- Thicken the sauce when beaten in near the end, adding richness and body.
The step that matters
Thicken with the egg yolks. Egg yolks thicken through gentle heat; if the sauce is too hot when they are added, they can scramble and turn grainy. Add them off the heat or at low heat, stirring constantly.
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.
