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 ↓
Baked Fish
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the fish
Preheat the oven to 350°F (175°C).
Clean, wash, and dry the fish. Split it down the middle.
Sprinkle the fish with salt and lay it inside down on a buttered baking dish.
Stuff and bake
Mix bread crumbs, butter, salt, chopped salt pork, and egg to make the dressing. Add parsley and onions if desired.
Fill the fish with the dressing and sew it up.
Place the fish in a large baking dish, add water and a little salt.
Bake for 1.5 hours, basting frequently.
Finish and serve
After removing the fish, thicken the gravy and pour it over the fish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the dish, cooking through in the oven while staying moist under basting.
- Bread crumbs
- Absorb the butter and egg to form a binding dressing that holds its shape inside the fish.
- Egg
- Binds the dressing so it holds together when the fish is filled and baked.
- Butter
- Adds richness and moisture to the dressing and helps the crumbs brown lightly.
- Salt pork
- Adds fat and savory flavor that seasons the dressing as it cooks.
The step that matters
Basting during the bake. Frequent basting keeps the surface and fish moist as the water and juices reduce, helping prevent the flesh from drying out over 1.5 hours of oven heat.
Swap the parsley
The recipe marks parsley as optional. How well each one fits the dish's main ingredients (fish, bread, butter, pork, egg, onion):
- Capersfits about as well
- Parsleythe original
- Garlicfits about as well
- Thymefits about as well
Fit is the average pairing score against fish, bread, butter, pork, egg, onion. Candidates are from the same food group and used in at least 100 recipes.
