Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Bloater Sandwiches
Ingredients
Directions
Prepare the filling
Grill or fry the bloaters, then remove all skin and bones.
Chop the bloaters finely. If possible, pound them in a mortar until smooth; otherwise, beat well.
Add butter until a soft, smooth paste forms. Pass through a wire sieve and season to taste.
Assemble and cut
Spread the mixture on thin slices of bread, then cover with bread coated thickly with watercress butter.
Trim away the crusts and cut into circles, squares, or triangles.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bloaters
- Provide the main savoury filling, which is mashed into a smooth paste.
- Butter
- Binds the cooked fish into a soft, spreadable paste with a rich mouthfeel.
- Watercress butter
- Adds a fresh, peppery flavour and a moist layer to the top slice.
The step that matters
Pounding or beating the fish smooth. If the bloaters are left in coarse pieces, the paste will be grainy and hard to spread. Thorough pounding or beating breaks up the flesh and fat so the butter can emulsify into a smooth, even texture.
