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 bloaters
Grill or fry the bloaters until cooked.
Remove all skin and bones, then chop finely.
If available, pound 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.
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 flavour and the soft, fish-based filling of the sandwich.
- Butter
- Adds richness and, when worked in, turns the fish into a soft, spreadable paste.
- Watercress-butter
- Adds moisture and a fresh, peppery flavour to the bread covering the filling.
The step that matters
Pass through a wire sieve. Pounding or beating alone leaves fibres and lumps in the fish. Sieving breaks them down further, giving the smooth, even paste that spreads well and makes the sandwich pleasant to eat.
