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

What each ingredient does

Sardines
Main protein, providing the rich, savory flavor and the soft flesh of the dish.
Lemon juice
Acidity that brightens the oily flavor of the fish.
Butter
Fat that adds richness and helps the toast brown and taste savory.
Bread
Base that gives structure and a crisp, toasted texture under the fish.

The step that matters

Heat in the oven until thoroughly hot.. Fish heated gently stays moist and tender. Overheating toughens the flesh and can dry it out, and the toast underneath can scorch.

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.
