Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Lobster Sauce
Ingredients
Directions
Prepare the lobster and spawn butter
Cut the lobster into dice-sized pieces.
In a mortar, combine the lobster spawn, butter, and anchovies. Pound the mixture.
Sieve the mixture.
Make the sauce
In a stewpan, combine the diced lobster and stock.
Add butter rolled in flour. Heat over medium, stirring until it boils.
If not thick enough, add a little flour mixed with water and boil again.
Stir in the lobster spawn and simmer without boiling.
Add lemon pickle and squeeze in the juice of half a lemon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lobster
- Provides the main meat and flavour of the sauce.
- Butter
- Adds richness and fat, and rolled in flour it thickens the sauce.
- Flour
- Thickens the stock as the sauce comes to a boil.
- Anchovies
- Add a salty, savoury depth when pounded with the spawn and butter.
- Stock
- Forms the liquid base that the sauce is built on.
- Lemon
- Adds acidity that brightens the rich sauce.
The step that matters
Stirring in the spawn without boiling. Egg-rich or delicate mixtures can curdle or turn grainy if boiled hard, so the spawn mixture should only simmer gently in the sauce to keep it smooth.
