Name: Mushrooms on Toast
Ingredients: 1 lb fresh mushrooms; 2 oz butter; ¼ teaspoon mace; ¼ teaspoon pepper; ¼ teaspoon coarse sea salt; ½ pint single cream or new milk (or beef gravy); a very small amount of grated lemon rind

Why it works: Pepper and lemon 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 ↓

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

What each ingredient does

Mushrooms: Release their moisture as they cook, softening and concentrating their earthy flavour.
Butter: Provides a rich fat for sautéing and carries flavour through the dish.
Single cream: Adds richness and moisture, and thickens slightly as the mixture stews.
Mace: Adds a warm, aromatic spice flavour.

The step that matters

Sautéing the mushrooms. Mushrooms are mostly water. If the pan is crowded or the heat is too low, they steam and release liquid instead of browning. Cooking them hot and in a single layer drives off moisture and develops savoury, browned flavour before the cream is added.

Swap the mace
