Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Deviled Sardines on Toast
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.
Make the filling
Remove skins from the sardines and pound them to a paste.
Pound the yolks of the hard-boiled eggs and mix with the sardine paste.
Add salt, white pepper, cayenne, and parsley; mix well.
Bake and serve
Spread the mixture on buttered toast.
Place in a 400°F (200°C) oven until thoroughly hot, then serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sardines
- Provide the main savory body and rich fish flavor of the filling.
- Hard-boiled egg yolks
- Add creamy richness and body that binds the sardine paste into a spreadable mixture.
- Buttered toast
- Gives a crisp, golden base and fat that carries the filling.
The step that matters
Heating until thoroughly hot. The filling is already cooked fish and egg, so heating it until it is evenly hot without drying the toast is what makes it safe and pleasant to eat. Watch the toast edges, which brown faster than the filling warms.
Swap the white pepper
How well each one fits the dish's main ingredients (egg, pepper, parsley):
- Dillfits better
- Tarragonfits better
- Marjoramfits better
- White pepperthe original
Fit is the average pairing score against egg, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
