Why it works: Thyme and marjoram match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 2,225 recipes mention both. Both carry terpineol, which smells pine, woody. The science ↓
The recipe
Ingredients
Contains: wheat, fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare
Wash and clean the redfish, then cut it into fine pieces.
Make the base
In a deep pot, heat the lard over medium heat.
Gradually add the flour, stirring constantly to make a roux without burning.
Add the mashed allspice, thyme, parsley, bay leaves, garlic, and onion to the roux.
Stir in the chopped tomatoes and cook for a few minutes.
Pour in the claret and water, then bring to a boil.
Finish the soup
Season with salt and cayenne to taste, then add the fish slices one by one.
Cook for about 5 minutes, then add the lemon juice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Redfish or red snapper
- Provides the main body of the soup, becoming tender as it cooks in the broth.
- Lard
- Carries fat for cooking the roux and adds richness to the soup.
- Flour
- Thickens the broth as it cooks into a roux with the fat.
- Tomatoes
- Add acidity, body, and a bright flavor to the broth.
- Claret
- Adds acidity and wine flavor to the broth.
- Onion
- Builds a sweet, savory base flavor with the roux and aromatics.
The step that matters
Making the roux. Flour cooked in fat must be stirred constantly over medium heat. If it burns, it turns bitter and dark, and it cannot be fixed, so the soup's flavor and color suffer.

Fit is the average pairing score against snapper, flour, allspice, thyme, parsley, marjoram, garlic. 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).
