Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Halibut head and shoulders
- Provides the main body of the dish, becoming tender and flavoring the cooking liquid as it stews.
- Beer
- Forms the stewing liquid and adds a malty, savory flavor to the sauce.
- Butter
- Adds richness and, kneaded with flour, thickens the sauce as it melts into it.
- Flour
- Thickens the sauce when cooked with butter, giving it body.
- Lemon juice
- Adds acidity that brightens the rich, savory sauce.
- Mushroom ketchup
- Adds deep, savory umami flavor to the sauce.
The step that matters
Bring the sauce to a boil. Flour-thickened sauce must be brought to a boil so the starch granules swell and fully thicken it. Adding lemon juice and mushroom ketchup before boiling lets them blend in evenly.
Swap the onion
How well each one fits the dish's main ingredients (beer, clove, parsley, pepper, butter, flour, lemon):
- Shallotfits better
- Carrotfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against beer, clove, parsley, pepper, butter, flour, lemon. Candidates are from the same food group and used in at least 100 recipes.
