Why it works: Flour and nutmeg are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 18,623 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Shrimp and Asparagus Sauce
Ingredients
Directions
Prepare
Cut the asparagus into short pieces.
Boil the asparagus in weak broth until tender.

Pound the shells.
Make the sauce
Heat the shells with 2 tablespoons of butter for a few minutes.
Strain the mixture through a fine sieve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce with fat and carries the flavour of the shells.
- Flour
- Thickens the butter and shrimp mixture into a smooth sauce.
- Asparagus
- Provides the main vegetable body and fresh, green flavour in the sauce.
- Shrimps
- Supply the main seafood flavour and tender meat for the sauce.
The step that matters
Adding the flour to the shrimp-butter. Flour must be cooked into the fat before liquid is added, otherwise it stays raw-tasting and forms lumps instead of a smooth, thickened sauce.
Swap the nutmeg
How well each one fits the dish's main ingredients (asparagus, shrimp, butter, flour):
- Capersfits better
- Tarragonfits better
- Garlicfits about as well
- Nutmegthe original
Fit is the average pairing score against asparagus, shrimp, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
