Ingredients: 2 cups salmon, fresh or canned; ½ cup milk; ½ cup stale bread crumbs; ½ teaspoon lemon juice; 1 beaten egg; ¼ teaspoon onion juice; Salt and pepper to taste

Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

Preheat the oven to 350°F (175°C).

Mix and bake

In a bowl, mix together the salmon, milk, bread crumbs, lemon juice, beaten egg, onion juice, salt, and pepper.
Transfer the mixture to a greased baking dish or greased tins or custard cups.
Bake for about 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Salmon: Forms the body of the loaf and provides the main protein structure.
Egg: Binds the mixture together and helps it set firm when baked.
Bread crumbs: Absorb the milk and add softness, keeping the loaf moist.
Milk: Adds moisture so the loaf stays tender rather than dry.
