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 ↓

The flavor team
The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Soles
- The main ingredient, with delicate white flesh that cooks quickly and flakes when done.
- Flour
- Forms a thin coating that browns during frying, giving the golden crust.
- Maitre d' hotel butter
- Adds richness and moisture, softening and flavouring the fish from inside as it heats.
- Essence of fish or anchovies
- Adds savoury, fishy depth to the liquid surrounding the soles.
The step that matters
Frying until golden. The flour coating browns through the Maillard reaction, which needs hot fat. If the fat is too cool, the soles turn greasy and soggy; if too hot, the coating burns before the fish cooks through.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
