Why it works: Capers and lettuce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 372 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Fish Sandwiches
Ingredients
Directions
Remove bones from anchovies or sardines and pound them into a paste.
Moisten the paste with a little lemon juice or mix with chopped pickles, olives, or capers.
Spread the mixture between slices of toasted bread or crackers, or on buttered bread or crackers.
For shad roe, season finely with salt, pepper, and lemon juice, and spread between lettuce leaves if desired.
Serve with bread or crackers alongside fresh boiled fish.
