Why it works: Onion and garlic match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 29,058 recipes. Both carry furaneol, which smells caramel, strawberry. The science ↓
Stewed Hard Shell Crabs
Ingredients
Directions
Prepare the crabs
Scald and clean the crabs by removing the top shell and claws.
Pick the meat from the claws.
Cook
Fry the meat with the bodies of the crabs in butter, along with the onion and garlic.
Add the browned flour, coloring pepper, water, bay leaves, parsley, and tomatoes.
Let the mixture simmer for about 1½ hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard shell crabs
- Provide the main meat and body flavor of the stew.
- Butter
- Fat that carries the frying of the crab meat and aromatics, adding richness.
- Browned flour
- Thickens the stew and adds a toasted, nutty flavor.
- Tomatoes
- Add acidity and liquid that build the body of the stew.
The step that matters
Frying the crab meat in butter. Frying in butter with the onion and garlic browns the surfaces and builds flavor compounds before liquid is added. Cooking too briefly or too hot can leave the aromatics raw or scorched, so the base tastes flat or bitter.
Swap the tomato
How well each one fits the dish's main ingredients (crab, pepper, onion, garlic, butter, flour, parsley):
- Okrafits better
- Chivefits better
- Shallotfits better
- Tomatothe original
Fit is the average pairing score against crab, pepper, onion, garlic, butter, flour, parsley. Candidates are from the same food group and used in at least 100 recipes.
