Why it works: Butter and potato are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 6,456 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
German Baked Pike Aux Sardines
Ingredients
Directions
Prepare the fish
Salt the pike moderately and bend it into a circle, securing the tail in the mouth.
Stew and bake
Place the pike in a buttered pan, cover it, and stew the fish.
If there is little gravy, add pea-water or plain water.
A quarter hour before serving, mash the sardines with butter and pour over the fish.
Bake uncovered until brown, basting constantly.
Serve
Serve garnished with chopped hard-boiled eggs and lightly fried potatoes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pike
- Forms the main body of the dish, providing firm, flaky white flesh when cooked.
- Sardines
- Mashed with butter and poured over the fish, adding rich, savoury flavour and moisture.
- Butter
- Greases the pan, enriches the sauce, and helps the fish brown while basting.
- Potatoes
- Fried as a side, adding crisp browned texture to the plate.
The step that matters
Basting constantly during the bake. Frequent basting keeps the surface moist and carries fat over the fish, so it browns evenly without drying out. Stopping early leaves the flesh dry and pale.
Swap the potato
How well each one fits the dish's main ingredients (butter, egg):
- Asparagusfits better
- Chivefits better
- Leekfits about as well
- Potatothe original
Fit is the average pairing score against butter, egg. Candidates are from the same food group and used in at least 100 recipes.
