Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Stewed Carp with Sardine Sauce
Ingredients
Directions
Prepare the fish
Cut the carp into pieces and season with coarse sea salt.
Melt ¼ cup of butter in a stewpan, add the fish, cover, and stew.
Make the sauce
In another pan, melt the remaining butter, then mix in the flour and bread crumbs, browning slightly.
Add the fish juice and water to the mixture, stirring well.
Mash the sardines with butter and mix into the sauce, adding wine if desired.
Pour the sauce over the fish and cook thoroughly.
Serve
Before serving, strain the sauce through a fine sieve and pour it over the fish on a serving dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carp
- Provides the main body of the dish, cooked gently by stewing so it stays moist.
- Butter
- Adds richness and fat, carrying flavour and helping the sauce brown lightly.
- Fine flour
- Thickens the sauce when cooked with butter, giving it body.
- Bread crumbs
- Toasted lightly with the flour, they add browning and a slightly nutty flavour to the sauce.
- Sardines
- Mashed into the sauce, they add a deep savoury, salty flavour.
The step that matters
Browning the flour and bread crumbs in butter. Cooking the flour and crumbs in fat until lightly browned develops nutty flavour and colour and cooks out raw starch taste. Stopping too early leaves the sauce pale and floury, while going too far makes it bitter.
