Why it works: Celery and tomato are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 3,377 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Green Turtle Soup
Ingredients
Directions
Prepare the turtle
Cut the turtle meat into dice-sized pieces.
Simmer with a little stock for 10 minutes.
Make the soup
Melt the butter in a pot and add sliced vegetables, ham, and veal bone.
Brown the mixture thoroughly.
Mix in the flour after browning.
Pour in the boiling stock and add celery, tomatoes, whole peppers, and allspice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green turtle
- Provides the main meat, which is cut into pieces and added to the finished soup.
- Butter
- Melted fat that starts the browning of the vegetables, ham, and veal bone for flavour.
- Flour
- Stirred in after browning to thicken the soup as it cooks.
- Sherry
- Adds aromatic, slightly sweet and acidic notes stirred in at the end.
- Madeira
- Adds rich, nutty sweetness stirred in at the end.
- Lemon juice
- Adds acidity that brightens the rich, long-cooked soup.
The step that matters
Brown the mixture thoroughly. Browning the vegetables, ham, and veal bone develops deep roasted flavours through the Maillard reaction. Pale browning leaves the finished soup flat and lacking depth.
Swap the allspice
How well each one fits the dish's main ingredients (butter, ham, veal, flour, celery, tomato, pepper):
- Parsleyfits better
- Thymefits better
- Tarragonfits better
- Allspicethe original
Fit is the average pairing score against butter, ham, veal, flour, celery, tomato, pepper. Candidates are from the same food group and used in at least 100 recipes.
