Ingredients
Directions
Prepare the sardines
Remove the gills and bones from the sardines and place them on a plate.
Sprinkle the sardines with lemon juice and a little cayenne pepper.

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, oily flesh that forms the topping of the dish.
- Butter
- Adds fat and richness to the toast and helps it taste savoury.
- Bread
- Gives a crisp, absorbent base that holds the warm sardines.
- Lemon juice
- Adds acidity that brightens the rich, oily flavour of the sardines.
- Anchovy paste
- Adds a deeper, salty umami note when used as an optional variation.
The step that matters
Heating the sardines until thoroughly hot. Sardines are already cooked and are heated only to warm them through. Heating them fully without drying them out keeps the flesh moist and the toast from becoming soggy, so check that they are steaming hot before serving.
