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, shellfish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the cod
Wash and clean the cod sounds.
Boil them in milk and water until nearly done.
Let them cool.
Make the force-meat
Mix bread crumbs, butter, salt, nutmeg, white pepper, and chopped oysters to make a force-meat.
Beat the egg yolks.
Mix the beaten yolks into the force-meat to bind it.
Spread the force-meat over the cod sounds.
Roll and bake
Roll the coated cod sounds up.
Secure the roll with a skewer.
Baste the roll with melted butter.
Roll the basted roll in seasoned bread crumbs.
Place the roll in a Dutch oven.
Baste with a feather dipped in melted butter.
Sprinkle additional bread crumbs on top.
Bake until golden brown.
Serve with oyster sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod sounds
- Forms the main body of the dish, cooked gently in milk and water before rolling.
- Bread crumbs
- Build the binding force-meat and form a crisp, browned crust on the outside.
- Butter
- Adds richness and moisture, and helps the crumb coating brown during baking.
- Egg yolks
- Bind the force-meat so it holds together around the fish when rolled.
- Chopped oysters
- Add a briny, savoury flavour to the stuffing.
The step that matters
Securing the roll before baking. A loosely rolled fillet can unwind and split in the oven, letting the force-meat spill out. A skewer holds the layers together so the roll cooks as one piece and keeps its shape.

Fit is the average pairing score against milk, bread, butter, nutmeg, oyster, 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).
