Why it works: Tomato and celery 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body and acidic tomato flavour of the soup.
- Milk
- Forms the creamy base that gives the bisque its smooth, rich body.
- Corn starch
- Thickens the milk as it cooks, giving the soup its body.
- Baking soda
- Neutralises some tomato acidity, softening the flavour and colour of the soup.
- Butter
- Adds fat and richness, rounding out the flavour and mouthfeel.
The step that matters
Thicken the milk with corn starch. Corn starch must be stirred constantly while cooking so it does not clump or scorch on the bottom of the pan. Starch granules only thicken evenly when they are dispersed and heated fully, so the milk becomes smooth and lightly thickened.
Swap the clove
How well each one fits the dish's main ingredients (tomato, sugar, celery, milk, onion, corn, butter):
- Cinnamonfits better
- Thymefits better
- Cuminfits better
- Clovethe original
Fit is the average pairing score against tomato, sugar, celery, milk, onion, corn, butter. Candidates are from the same food group and used in at least 100 recipes.
