Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Carries the onion and spices and gives the base a rich, savory flavor.
- Onion
- Softens and browns to add sweetness and depth to the sauce.
- Flour
- Thickens the stock into a smooth sauce as it cooks with the butter.
- Curry powder
- Supplies the warm, aromatic spice flavor that defines the dish.
- Stock
- Forms the liquid body of the curry sauce.
- Lobster
- Provides the main protein and its delicate sweet flavor.
The step that matters
Stir in the flour and curry powder until smooth and brown. Flour must be cooked into the fat so it thickens smoothly without lumps or a raw taste. Toasting the curry powder in fat also wakes up its aromatic compounds, so stir constantly and do not let the mixture scorch.
Swap the onion
How well each one fits the dish's main ingredients (butter, flour, lobster):
- Shallotfits better
- Chivefits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against butter, flour, lobster. Candidates are from the same food group and used in at least 100 recipes.
