Why it works: Crab and butter work together. They rank in the top 10% of all ingredient pairs, and cooks put them together in 812 recipes. Both carry nonanal, which smells fat, citrus. The science ↓
Stewed Crabs
Ingredients
Directions
Prepare the crabs
Boil the crabs and remove the shells.
Clean the crabs thoroughly, cut the bodies in halves, and crack the claws.
Make the sauce
In a saucepan, melt the butter over medium heat.
Add the flour to the hot butter and stir until it turns yellow.
Add the canned tomatoes, crabs, and enough water to cover the crabs.
Season with salt and paprika, then cook for 15 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the sauce as it cooks with the butter and liquid.
- Butter
- Adds richness and fat, and carries flavour into the flour roux.
- Canned tomatoes
- Provide acidity, moisture and body to the sauce.
- Hard-shelled crabs
- Supply the main protein and flavour of the dish.
The step that matters
Stirring the flour into the butter. Flour must be stirred continuously in the hot butter so it cooks evenly into a roux. Undercooked flour tastes raw and does not thicken well, while overcooked flour loses thickening power and can scorch.
Swap the tomato
How well each one fits the dish's main ingredients (crab, butter, flour):
- Okrafits better
- Chivefits better
- Shallotfits better
- Tomatothe original
Fit is the average pairing score against crab, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
