Why it works: Fish and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 4,488 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
To Bake Fish
Ingredients
Directions
The book says “a gentle oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
Wrap small fish in oiled or buttered paper.
For larger fish, place them in a deep dish with or without liquid.
Cover the fish with buttered paper to keep the surface moist.
If using large pieces, bake them over halved potatoes.
Bake and serve
Bake until the fish is cooked through and moist.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Is the main protein that cooks through gently and stays moist under paper.
- Butter
- Adds moisture and richness to the paper wrapping and the fish surface.
- Potatoes
- Raise large pieces of fish above the dish base so they bake more evenly.
The step that matters
Covering the fish with buttered paper. Paper shields the surface from direct heat, so moisture stays in and the fish cooks gently instead of drying out at the edges.
