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

What each ingredient does

Sardines
Provide the main protein and rich, oily flavour that the dish is built around.
Lemon juice
Adds acidity that brightens the rich, oily flavour of the sardines.
Butter
Adds fat and richness to the toast and helps it taste warm and savoury.
Bread
Forms the crisp, absorbent base that holds the sardines.

The step that matters

Heat the sardines in the oven until thoroughly hot. Sardines are fish that can dry out or toughen with excess heat, while under-heating leaves them cool in the middle. Heating only until thoroughly hot keeps them moist and safe to eat.

Swap the lemon

How well each one fits the dish's main ingredients (pepper, butter, bread):

  1. Lemonthe original
  2. Figfits about as well
  3. Plumfits less well
  4. Mangofits less well

Fit is the average pairing score against pepper, butter, bread. Candidates are from the same food group and used in at least 100 recipes.
