Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 27,039 recipes mention both. Both carry 2-nonenal, which smells fatty, green. The science ↓
The recipe
Ingredients
Contains: egg, milk, wheat, fish, shellfish (auto-detected from the ingredients and method; we can miss things, so check labels)

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Forms the main body of the roll, giving it a firm, flaky structure once steamed.
- Egg yolks
- Bind the mixture together and add richness and a tender set when cooked.
- Breadcrumbs
- Absorb the milk and bulk out the fish, helping the roll hold together with a soft texture.
- Milk
- Adds moisture and softness to the breadcrumb and fish mixture.
- Butter
- Adds fat for richness and a smooth mouthfeel.
The step that matters
Steam for 40 minutes. Steaming gently cooks the egg-bound fish mixture so it sets firm without drying or becoming rubbery. The cloth must be wrapped snugly so the roll keeps its shape.

Fit is the average pairing score against milk, lemon, butter, pepper, anchovy, nutmeg, 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).
