Why it works: Mace and clove are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 8,400 recipes. Both carry methyleugenol, which smells clove, spice. The science ↓
Tomato Soup
Ingredients
Directions
Make the fish stock
Chop the fish bones and trimmings and place them in a stewpan with 3 pints of water.
Add the peeled onion, the cloves, the mace and the bouquet garni.
Bring the mixture to a boil and skim the surface.
Reduce the heat and simmer for about 30 minutes.
Make the soup
Slice the tomatoes.
Melt the butter in a separate stewpan, increase the heat and sauté the tomatoes in the butter.
Strain the fish stock into the tomatoes.
Mix the milk with the flour and add the mixture to the soup.
Stir until it begins to boil, then skim the soup.
Cook slowly for half an hour.
Season with pepper and salt.
Rub the soup through a fine sieve.
Bring to a boil again and stir in the tapioca.
Simmer for another 10 minutes before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main flavour, body and acidity of the soup.
- Butter
- Carries the flavour of the tomatoes and adds richness to the soup.
- Flour
- Thickens the soup with milk to give it body.
- Milk
- Adds creaminess and softens the tomato flavour.
- Crushed tapioca
- Thickens the soup further as it heats.
- Fish bones and trimmings
- Build the savoury stock that forms the base of the soup.
The step that matters
Stir in the milk and flour mixture until it boils. Flour thickens only when heated, and it can clump if added without mixing it smoothly with the milk first. Stirring while the soup comes to a boil keeps it smooth and evenly thickened.
Swap the mace
How well each one fits the dish's main ingredients (tomato, fish, flour, butter, milk, onion, clove):
- Cinnamonfits better
- Cardamomfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against tomato, fish, flour, butter, milk, onion, clove. Candidates are from the same food group and used in at least 100 recipes.
