Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Fried Cod’s Roe
Ingredients
Directions
Prepare the roe
Boil the cod's roe until cooked, then let it cool completely.
Cut the roe into slices about ½ inch thick.
Dip each slice into the beaten egg, then coat with white bread crumbs.
Fry and serve
Melt the butter in a frying pan over medium heat.
Fry the slices of roe until golden brown on one side, then flip and fry the other side.
Drain on a wire strainer.
Arrange the fried roe in a circle on a serving dish with fish paper underneath and garnish with parsley in the center.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod's roe
- Forms the main body of the dish, cooked and then fried to a firm, crisp-edged slice.
- Egg
- Binds the bread crumbs to the roe so the coating holds during frying.
- White bread crumbs
- Form a crisp, golden coating that browns in the hot butter.
- Butter
- Conducts heat to the coating and adds richness and browning flavor.
The step that matters
Let the roe cool completely before slicing and coating. Warm roe is soft and crumbles, and a wet or warm surface makes the egg and crumbs slide off or steam instead of crisping in the pan.
Swap the parsley
How well each one fits the dish's main ingredients (roe, egg, bread, butter):
- Nutmegfits about as well
- Parsleythe original
- Capersfits about as well
- Thymefits less well
Fit is the average pairing score against roe, egg, bread, butter. Candidates are from the same food group and used in at least 100 recipes.
