Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Lobster Croquettes
Ingredients
Directions
Make the filling
In a saucepan, melt the butter and stir in the flour until well combined.
Add enough milk or cream to create a creamy mixture.
Stir in the chopped lobster, salt, cayenne pepper, and lemon juice.
Allow the mixture to cool, then shape it into croquettes.
Coat and fry
Roll each croquette in the beaten egg and then in cracker crumbs.
Fry the croquettes in hot oil until golden brown.
Drain the fried croquettes on paper towels.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lobsters
- Provides the main flavor and the bulk of the filling.
- Butter
- Enriches the sauce base and adds richness to the filling.
- Flour
- Thickens the butter and milk mixture so the filling holds its shape.
- Milk or cream
- Makes the flour-thickened base creamy and moist, binding the lobster.
- Egg
- Binds the crumb coating to the croquette so it stays on during frying.
The step that matters
Cool the filling before shaping. A warm, loose filling will not hold its shape and can break apart in the oil. Cooling lets the starch set so the croquettes keep their form and fry cleanly.
