Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Okra
Releases natural thickening that gives the gumbo its body as it simmers.
Onions
Browning in butter builds sweetness and savory depth in the base.
Crabs
Contribute rich seafood flavor to the broth as they cook through.
Butter
Carries the browning of the onions and okra and adds richness.
Veal knuckle
Adds gelatin and meaty body to the stock.

The step that matters

Browning the onions and okra. Sautéing until browned develops deep, roasted flavor through the Maillard reaction; pale vegetables produce a flatter soup. Okra also gives off slime, which is softened by thorough cooking.

Swap the okra
