Why it works: Fish and sorrel work together. They rank in the top 17% of all ingredient pairs, and 25 recipes mention both. Both carry acetaldehyde, which smells pungent, ethereal. The science ↓
The recipe
Ingredients
Contains: egg, milk, fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Make the broth
Clean and wash the fish thoroughly.
Stew the fish with carrots, lettuces, leeks, onions, and sorrel in enough water to cover them until everything is soft.
Strain the mixture through a coarse cloth.
Boil the liquid, covered, for 1 hour.
Finish the soup
Cut some of the vegetables small.
Sauté the cut vegetables in butter.
Simmer the sautéed vegetables in the soup for 1 hour with pepper, salt, and cloves.
Soften the French roll in good broth.
Mix the yolks of 6 eggs with a few crumbs.
Stir the egg yolk mixture into the soup.
Pour the soup over the softened roll before serving.
If using peas, add the pulp and some of the water they were boiled in to achieve the desired consistency.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks thicken the soup and add richness when stirred in.
- Butter
- Fat that softens and carries flavor from the sautéed vegetables.
- French roll
- Absorbs broth, becoming soft and giving the soup body.
- Fish
- Provides the main savory flavor in the broth.
The step that matters
Stirring the egg yolk mixture into the soup. Egg yolks thicken when heated gently; adding them to very hot soup without tempering or constant stirring can cause them to scramble into grainy lumps.

Fit is the average pairing score against fish, carrot, lettuce, leek, onion, sorrel, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
