Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sardines
- Provide the main savoury flavour and the paste base, with reserved strips for topping.
- Hard-boiled egg yolks
- Bind with the fish and butter to give the paste a smooth, creamy texture.
- Butter
- Adds richness and fat, helping the paste turn smooth and spreadable.
- Mustard
- Adds sharp, pungent flavour that cuts the richness of the fish and butter.
- Vinegar
- Adds acidity that brightens the flavour of the rich paste.
The step that matters
Toast or fry the bread until golden. The bread must be firm and lightly browned so it stays crisp under the moist paste; under-toasted bread softens quickly and turns soggy.
