Why it works: Bread and butter match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 27,145 recipes mention both. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
The recipe
Ingredients
Contains: egg, milk, wheat, fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare bread croûtons as in the preceding recipe.
Spread each croûton thinly with fresh butter.
Add a layer of potted cod's roe paste on top.
Garnish with slices of hard-boiled eggs and finely chopped parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
Flavor stand-ins for the parsley
How well each one fits the dish's main ingredients (bread, butter, roe, egg):
- Nutmegabout as good a flavor fit
- Parsleythe original
Fit is the average pairing score against bread, butter, roe, egg. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
