Why it works: Mustard and capers match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 624 recipes mention both. Both carry coumarin, which smells sweet, hay. The science ↓
Calf's Tongue and Brains with Tartar Sauce
Ingredients
Directions
Soak the brain in salted water for 1 hour, then remove the thin membrane carefully.
In a saucepan, combine the brain with 1 quart of cold water, 1 teaspoon of salt, and 1 tablespoon of vinegar. Parboil for 15 minutes.
Serve the tongue cold in the center of a dish, with the brains cut in half on the sides.
Prepare the Tartar Sauce by mixing the egg yolk, dry mustard, salt, and cayenne in a bowl until smooth.
Gradually add the salad oil and lemon juice while stirring until thick and smooth.
Mix in the chopped parsley, capers, gherkin, and onion. Keep cool until ready to serve.
Garnish the dish with parsley.

Fit is the average pairing score against vinegar, egg, mustard, pepper, lemon, parsley, capers. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
