Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod steaks
- Forms the main protein, which flakes once cooked through in the gravy.
- Onions
- Browning when fried adds sweetness and savory depth to the dish.
- Curry powder
- Supplies the warm, aromatic spice flavor that defines the dish.
- Cream
- Adds richness and body to the gravy, softening the heat of the spices.
- Flour
- Thickens the liquid into a gravy that clings to the fish.
The step that matters
Frying the cod and onions to a good brown. Browning through the Maillard reaction builds deep, savory flavor. Stopping too early leaves the base pale and bland, while overcooking dries the fish and makes the onions bitter.
Swap the onion
How well each one fits the dish's main ingredients (pepper, cream, butter, flour):
- Spinachfits better
- Leekfits better
- Potatofits better
- Onionthe original
Fit is the average pairing score against pepper, cream, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
