Why it works: Butter and fish are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 4,488 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Soles
- The main fish, cooked whole and then opened and filled with butter.
- Flour
- Forms a coating that browns and crisps during frying.
- Maitre d' hotel butter
- Adds richness and fat that melts into the fish as it is served hot.
- Lemon juice
- Adds acidity that brightens the rich butter and fish.
- Essence of fish or anchovies
- Adds concentrated fish flavour to the liquid poured around the soles.
The step that matters
Fry the floured soles until golden brown. The flour coating needs enough heat to brown and crisp, but overcooking dries the delicate flesh. Getting this balance keeps the fish moist and the coating crisp.
Swap the lemon
How well each one fits the dish's main ingredients (flour, butter, fish):
- Raisinfits better
- Coconutfits about as well
- Lemonthe original
- Vanillafits less well
Fit is the average pairing score against flour, butter, fish. Candidates are from the same food group and used in at least 100 recipes.
