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 ↓
Sardine Toast
Ingredients
Directions
Prepare the sardine paste
Trim and scale the sardines, remove the bones, and pound them to a paste with 1 oz of butter.
Assemble the toast
Toast and butter the bread, then cut it into triangles.
Spread the sardine paste over the toast.
Make and pour the sauce
In a saucepan, melt the remaining butter, add the flour, and gradually stir in the water to make a sauce.
Flavor the sauce with anchovy essence, Yorkshire Relish, lemon juice, and season with cayenne pepper.
Pour the sauce over the toast and serve very hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sardines
- Provide the main fish flavor and a savory, rich paste that forms the topping.
- Butter
- Adds richness and carries flavor in both the sardine paste and the sauce.
- Flour
- Thickens the melted butter and water into a smooth sauce.
- Anchovy essence
- Adds concentrated salty, savory depth to the sauce.
- Bread
- Provides a crisp, absorbent base that holds the paste and sauce.
The step that matters
Make the sauce smooth. Flour must be cooked briefly in the melted butter before water is added gradually, so it thickens evenly without lumps or a raw starchy taste.
