Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Baked Mackerel
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Wash the mackerel well and soak for 12 hours.
Wash again and roll in flour, then lightly pepper.
Bake and serve
Place in a baking pan and add 1 teaspoon of butter and 2 cups of water for all mackerel.
Bake in a hot oven at 400°F (200°C) for about 20 minutes.
Serve on slices of toasted and buttered bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mackerel
- Is the main protein, cooked gently in the pan with water and butter.
- Flour
- Coats the fish, helping the outside brown and the surface stay lightly crisp.
- Butter
- Adds richness and flavour to the fish as it bakes.
The step that matters
Bake in a hot oven at 400°F (200°C) for about 20 minutes. Baking at high heat for a set time cooks the fish through quickly. Too long dries out the flesh, while too short leaves it undercooked. Watching the fish closely helps it stay moist.
