Why it works: Egg and bread are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 22,662 recipes. Both carry (e)-2-octenal, which smells fatty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod roe
- Forms the main body of the cutlets, setting firm when poached and holding its shape when sliced.
- Beaten egg
- Acts as a sticky binder so the bread crumbs adhere to the slices.
- Bread crumbs
- Form a crisp, golden coating that browns during frying.
- Vinegar
- Adds a slight acidity to the cooking water, sharpening the flavour of the roe.
The step that matters
Fry the slices in boiling oil until golden brown. The oil must be hot enough to crisp the crumb coating quickly. If it is too cool, the coating absorbs oil and turns greasy before it browns.
Swap the parsley
How well each one fits the dish's main ingredients (roe, vinegar, egg, bread):
- Capersfits about as well
- Parsleythe original
- Tarragonfits about as well
- Nutmegfits about as well
Fit is the average pairing score against roe, vinegar, egg, bread. Candidates are from the same food group and used in at least 100 recipes.
