Why it works: Capers and butter are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 1,637 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Caper Sauce
Ingredients
Directions
Prepare the capers
Mince one-third of the capers very fine and halve the rest.
Make the sauce
Combine the capers with the melted butter or thickened gravy.
Stir gently to avoid separation.
Optionally, add minced parsley, chervil, or tarragon, or the juice of half a Seville orange or lemon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Capers
- Add a sharp, briny bite that cuts through the richness of the sauce.
- Vinegar
- Adds acidity that brightens the flavour and balances the fat.
- Butter
- Provides fat for richness and a smooth, silky mouthfeel.
The step that matters
Stir gently to avoid separation. Melted butter is an emulsion of fat and water. Vigorous stirring or excess heat can break it, so the sauce turns greasy and grainy. Gentle stirring keeps the fat evenly dispersed.
Swap the capers
How well each one fits the dish's main ingredients (vinegar, butter):
- Tarragonfits better
- Garlicfits about as well
- Parsleyfits about as well
- Capersthe original
Fit is the average pairing score against vinegar, butter. Candidates are from the same food group and used in at least 100 recipes.
