Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fowl
- Provides the main meat and flavour, and its flour coating helps it brown.
- Flour
- Coats the fowl so it browns and helps thicken the gumbo liquid.
- Butter and lard
- Fat for frying the onion and fowl, carrying flavour and aiding browning.
- Onion
- Adds sweetness and savoury depth as it softens in the hot fat.
- Oysters
- Add a briny, savoury flavour to the broth as they cook in it.
The step that matters
Fry the fowl until browned. Flour-dredged pieces need real browning in the fat before the water goes in. That colour and toasted flavour carry into the broth, and pale, under-fried pieces leave it tasting flat.
Swap the onion
How well each one fits the dish's main ingredients (pepper, flour, butter, oyster):
- Shallotfits better
- Okrafits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against pepper, flour, butter, oyster. Candidates are from the same food group and used in at least 100 recipes.
