Why it works: Capers and pepper are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 2,088 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Sardines with Capers
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Remove the skin and bones from the sardines and cut them in half.
Prepare the croutons or cut the toast into finger-shaped pieces.
Assemble
Place 4 sardine halves on each piece of toast.
Add a few grains of cayenne pepper.
Sprinkle liberally with grated Parmesan cheese.
Bake and serve
Cover with buttered paper and heat in a 400°F (200°C) oven until hot.
Heat the liquid meat glaze, stir in the capers, pour it over the sardines, and serve hot.

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 at the centre of the dish.
- Grated parmesan cheese
- Melts and browns under heat, adding savoury flavour and a golden crust.
- Liquid meat glaze
- Adds concentrated savoury depth and moisture to the sardines.
- Capers
- Add a sharp, acidic brightness that cuts through the richness of the fish.
The step that matters
Heating the Parmesan and sardines until hot. Covering with buttered paper traps steam so the fish heats through gently while the cheese melts. Overheating can dry the sardines and scorch the cheese, so check that the fish is hot without browning too far.
Swap the capers
How well each one fits the dish's main ingredients (meat, parmesan cheese, pepper):
- Basilfits better
- Celeryfits better
- Thymefits better
- Capersthe original
Fit is the average pairing score against meat, parmesan cheese, pepper. Candidates are from the same food group and used in at least 100 recipes.
