Why it works: Flour and nutmeg are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 18,623 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Provides the main body and flavour of the soup as it cooks in the broth.
- Shrimp
- Adds sweet, briny flavour from both the meat and the shells used for stock.
- Butter
- Carries flavour from the browned vegetables and adds richness to the broth.
- Flour
- Helps brown the vegetables and begins to thicken the broth.
- Arrowroot
- Thickens the broth to a smooth, glossy body without clouding it.
- White wine
- Adds acidity and aromatic depth that balances the rich fish broth.
The step that matters
Heat through without boiling. Fish and shrimp turn tough and dry when boiled, and boiling can break up the delicate pieces. Gentle heat cooks them through while keeping them tender.
Swap the nutmeg
How well each one fits the dish's main ingredients (fish, whiting, shrimp, butter, flour, sugar, white wine):
- Capersfits better
- Nutmegthe original
- Parsleyfits about as well
- Garlicfits about as well
Fit is the average pairing score against fish, whiting, shrimp, butter, flour, sugar, white wine. Candidates are from the same food group and used in at least 100 recipes.
