Why it works: Butter and flour 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 ↓
Mackerel, Baked
Ingredients
Directions
The book says “a moderate oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the fish
Clean the mackerel.
Remove the roes.
Stuff the fish with the forcemeat.
Sew up the opening.
Season and dress
Place the mackerel in a baking dish with the roes.
Add the butter or sweet dripping.
Dredge the mackerel with flour.
Sprinkle the mackerel with coarse sea salt and pepper.
Bake and serve
Bake at 400°F (200°C) for 30 to 40 minutes, basting occasionally.
Serve with parsley sauce or melted butter mixed with lemon juice and chopped parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mackerel
- Forms the main body of the dish and cooks into tender, flaky flesh.
- Veal forcemeat
- Fills the cavity, adding richness and moisture as the fish bakes.
- Butter or sweet dripping
- Adds fat that carries flavour and helps the skin brown and the fish stay moist.
- Flour
- Dries the fish surface, helping it brown and form a light crust.
The step that matters
Basting occasionally during baking. Basting spreads melted fat over the fish, keeping the surface from drying out and helping it brown evenly. Mackerel is lean and cooks quickly, so dryness is a real risk within the 30 to 40 minute bake.
