Why it works: Sorrel and chervil match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 247 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Sorrel Soup
Ingredients
Directions
Prepare and cook
Wash the sorrel and lettuce, then chop them finely.
In a stewpan, melt the butter and add the chopped sorrel and lettuce. Cook while stirring for about 5 minutes.
Add the stock, reduce the heat slightly, and let it simmer gently for about 30 minutes.
Pass the mixture through a fine sieve to create a puree.
Finish the soup
Return the puree to a clean stewpan and add the béchamel sauce. Season with salt, pepper, and a pinch of nutmeg, then reheat.
Add the tarragon and chervil, cleaned and cut into shreds, and cook for a few more minutes.
In a bowl, whisk the cream and egg yolks together, then stir them into the soup. Cook briefly to set the eggs, then serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sorrel
- Gives the soup its sharp, acidic flavour and green colour once cooked down.
- Butter
- Enriches the flavour and carries the greens while they soften in the pan.
- Béchamel sauce
- Adds body and a smooth, creamy texture to the puree.
- Egg yolks
- Thicken the soup when gently heated, giving it a richer, silkier body.
- Cream
- Adds richness and a smooth, velvety mouthfeel to the finished soup.
- Cabbage lettuce
- Adds bulk and mild vegetable sweetness to the puree.
The step that matters
Cooking the egg yolks into the soup. Egg yolks thicken when heated gently, but if the soup boils after they are added they can scramble and turn grainy. Keep the heat low and stir constantly while the eggs set.
Swap the cabbage
How well each one fits the dish's main ingredients (sorrel, tarragon, chervil, cream, pepper, nutmeg, lettuce):
- Shallotfits better
