Why it works: Mustard and capers match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 624 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Cold Mutton
Ingredients
Directions
Prepare the meat
Cut the cold mutton into thin slices, as evenly as possible.
Place a paste-cutter about an inch and a half in diameter in the middle of an oval dish.
Arrange the slices of meat around the dish, one slice lapping over another.
Fill the two empty places on the other two sides with chopped hard-boiled white and yolk of egg, kept separate, with the yolk farther from the paste-cutter.
Garnish the dish
Put a string of chopped yolk of egg all around the meat, then a string of chopped white of egg outside it, then chopped parsley around the white.
Remove the paste-cutter and put a rose, or two or three pinks, or a small bunch of violets in its place.
Place one or three capers on each small heap of yolk of egg in the middle of the dish, and capers here and there on the string of white of egg.
Place a rose at each end of the dish.
Place six radishes around the dish.
Make the sauce
Put half a teaspoonful of mustard, a little pepper and salt in a bowl.
Pour one or two tablespoonfuls of vinegar on, little by little, beating with a fork.
Add three or four tablespoonfuls of oil in the same way.
When the sauce is well mixed, serve it in a boat or saucer with the dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vinegar
- Adds sharp acidity that balances the richness of the oil and egg.
- Oil
- Forms the fat phase of the sauce, giving it body and a smooth texture.
- Mustard
- Helps the oil and vinegar bind into a stable, smooth emulsion.
- Eggs
- Chopped whites and yolks add colour and mild richness to the garnish.
The step that matters
Adding the vinegar and oil slowly while beating. Adding liquid gradually while beating breaks it into tiny droplets that stay suspended, so the sauce emulsifies. Adding it all at once lets the oil and vinegar separate.
Swap the radish
How well each one fits the dish's main ingredients (vinegar, mustard, capers, egg):
- Shallotfits better
- Horseradishfits better
- Lettucefits better
- Radishthe original
Fit is the average pairing score against vinegar, mustard, capers, egg. Candidates are from the same food group and used in at least 100 recipes.
