Why it works: Crab and meat work together. They rank in the top 8% of all ingredient pairs, and cooks put them together in 448 recipes. Both carry 2,3,5-trimethylpyrazine, which smells cocoa, roasted. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Crab meat
- Forms the main body of the filling, providing the dish's savory flavor.
- Flour
- Thickens the cream into a smooth sauce that holds the crab together.
- Cream
- Provides richness and moisture, forming the base of the sauce.
- Butter
- Adds fat and flavor, helping the flour blend smoothly into the sauce.
- Mustard
- Adds sharpness that balances the richness of the cream and crab.
The step that matters
Adding the flour-butter mixture to the cream. Stirring in hot cream gradually, rather than dumping it in, helps the flour dissolve evenly. Lumps form when starch clumps before it hydrates, and a smooth sauce depends on even thickening.
Swap the mustard
How well each one fits the dish's main ingredients (crab, meat, cream, flour, butter):
