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 ↓
Deviled Scallops
Ingredients
Directions
Prepare the scallops
Clean the scallops and heat them to boiling point, then drain and reserve the liquor.
Make the sauce
Melt the butter in a pan, then add the flour, salt, mustard, and cayenne.
Gradually pour in the reserved liquor while stirring.
When the sauce begins to thicken, add the scallops.
Serve
Serve with brown bread sandwiches.

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
- Scallops
- Provide the main protein, which sits in the sauce and is the dish's centrepiece.
- Butter
- Forms the fat base that carries the flour and gives the sauce richness.
- Flour
- Thickens the sauce as it cooks with the butter and liquor.
- Reserved scallop liquor
- Supplies the liquid that, stirred in, turns the roux into a sauce.
The step that matters
Adding the liquor gradually while stirring. Pouring the liquid in slowly and stirring keeps the flour-butter roux smooth, so the sauce thickens evenly without lumps.
Swap the mustard
How well each one fits the dish's main ingredients (scallop, butter, flour):
- Shallotfits better
- Chivefits better
- Potatofits better
- Mustardthe original
Fit is the average pairing score against scallop, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
