Why it works: Lemon and pepper 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 or Crab Sauce
Ingredients
Directions
Prepare
Remove the meat from the boiled lobster or crab and chop it.
If using raw lobster, remove the spawn.
Pound the spawn with a little butter.
Make the sauce
Melt the butter in a saucepan.
Stir in the flour to make a roux.
Gradually add the milk, stirring constantly until smooth.
Season the sauce with cayenne pepper, salt, and lemon juice.
Add the spawn to the sauce after the lobster.
Simmer the sauce for a few minutes until it turns bright red.
Add the cream just before serving.

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
- Butter
- Enriches the sauce and carries flavour as the base of the roux.
- Flour
- Thickens the sauce with the butter as a roux.
- Milk
- Forms the liquid body of the sauce, which thickens as it heats.
- Lobster or crab
- Provides the main shellfish meat and flavour of the sauce.
- Cream
- Adds richness and smoothness to the finished sauce.
The step that matters
Gradually add the milk while stirring constantly. Adding liquid slowly to a roux and stirring keeps the flour dispersed, so the sauce becomes smooth instead of lumpy.
