Why it works: Onion and mustard match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 9,259 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Remove the meat from the cooked crabs and set aside.
Place the shells and bony bits in a bowl and cover with hot water.
Make the filling
In a separate bowl, combine the crab meat, onion, cracker crumbs, black pepper, red pepper, coarse sea salt, butter, and mustard. Mix well.
Add a mixture of the hot water from the shells and half and half until the meat is moist.
Fill the crab shells with the mixture.
Bake and serve
Sift powdered crackers over the tops and place a bit of butter on each.
Bake at 400°F (200°C) until brown and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked crab meat
- Provides the main filling and savory seafood flavor of the dish.
- Cracker crumbs
- Absorb liquid and help bind the filling so it holds its shape.
- Butter
- Adds richness and fat that carries flavor and helps the tops brown.
- Half and half
- Adds moisture and creaminess to keep the filling tender after baking.
- Mustard
- Adds sharp, tangy flavor that balances the richness of the crab.
The step that matters
Moisten the filling to the right consistency. Adding too little liquid leaves the filling dry and crumbly, while too much makes it loose and soggy. Cracker crumbs absorb liquid as they sit, so the filling should be moist but still hold its shape in the shells.
Swap the onion
How well each one fits the dish's main ingredients (crab, meat, pepper, butter, mustard):
- Horseradishfits better
- Lettucefits better
- Capsicumfits about as well
- Onionthe original
Fit is the average pairing score against crab, meat, pepper, butter, mustard. Candidates are from the same food group and used in at least 100 recipes.
