Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Devilled Sardines
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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 400°F (200°C).
Remove the sardines from their can and place them on a baking dish.
Make and add the topping
In a bowl, mix softened butter, mustard, cayenne pepper, lemon juice, and salt.
Spread the mixture over the sardines.
Bake
Bake for 10-15 minutes until heated through and slightly browned.

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 flavor that the topping complements.
- Butter
- Adds fat and moisture, helping the topping spread and brown lightly in the oven.
- Mustard
- Adds sharp, pungent flavor that cuts through the richness of the fish and butter.
- Lemon juice
- Adds acidity that brightens the rich, oily sardines.
The step that matters
Bake for 10-15 minutes until heated through and slightly browned. Sardines are oily and cook quickly; overbaking dries the fish and toughens its flesh, while underbaking leaves the topping raw and the fish cold in the center. Watching for the topping to turn lightly golden signals doneness.
Swap the mustard
How well each one fits the dish's main ingredients (butter, pepper, lemon):
- Capsicumfits better
- Spinachfits better
- Asparagusfits better
- Mustardthe original
Fit is the average pairing score against butter, pepper, lemon. Candidates are from the same food group and used in at least 100 recipes.
