Bloater Sandwiches

Ingredients

Directions

Prepare the filling

  1. Grill or fry the bloaters, then remove all skin and bones.

  2. Chop the bloaters finely. If possible, pound them in a mortar until smooth; otherwise, beat well.

  3. Add butter until a soft, smooth paste forms. Pass through a wire sieve and season to taste.

Assemble and cut

  1. Spread the mixture on thin slices of bread, then cover with bread coated thickly with watercress butter.

  2. Trim away the crusts and cut into circles, squares, or triangles.

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.
