Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Sauce Tartare
Ingredients
Directions
Make the base
In a saucepan, combine vinegar, melted butter, salt, and cayenne pepper.
Beat the eggs separately and add the yolks to the mixture.
Cook over low heat until it thickens, then remove from heat and let cool.
Finish
Once cool, fold in the whipped cream and add capers to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the sauce on gentle heat and help bind the butter into it.
- Melted butter
- Adds fat and richness, giving the sauce a smooth, silky body.
- Vinegar
- Adds sharp acidity that cuts through the richness of the eggs and butter.
- Whipped cream
- Adds lightness and a soft texture when folded in after cooling.
The step that matters
Cooking the yolks over low heat. Egg yolks set and can curdle or scramble if they get too hot too fast. Gentle heat and constant stirring let them thicken evenly into a smooth sauce.
Swap the capers
How well each one fits the dish's main ingredients (vinegar, butter, pepper, egg, cream):
- Tarragonfits better
- Parsleyfits better
- Nutmegfits better
- Capersthe original
Fit is the average pairing score against vinegar, butter, pepper, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
