Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Sardines
Provide the main fish flavor and the body of the filling.
Lemon juice
Adds acidity that brightens the rich, oily flavor of the fish.
Melted butter
Adds fat and moisture, giving the mashed filling a smoother, spreadable texture.
Rye or whole-wheat bread
Holds the filling and adds a sturdy, chewy contrast to the soft spread.

The step that matters

Remove the skin and bones. Bones and skin are hard or tough when eaten, and they are easy to miss once the sardines are mashed. Removing them first keeps the filling smooth and safe to eat.

Swap the lemon
