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 ↓
To Bake Mackerel
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Fill the cleaned mackerel with forcemeat and sew them up.
Arrange the mackerel closely in a buttered baking dish.
Lightly flour the mackerel and sprinkle with coarse sea salt.
Dot with butter or pour melted butter over the mackerel.
Bake and serve
Bake in a 350°F (175°C) oven for 30 minutes.
Carefully lift the mackerel to a hot dish and serve with melted butter.

What each ingredient does
- Mackerel
- Forms the main body of the dish and provides the flesh that cooks through in the oven.
- Forcemeat
- Fills the fish, adding moisture and a seasoned, tender texture as it cooks inside.
- Butter
- Adds richness and moisture, helping the fish stay tender and brown lightly in the oven.
- Flour
- Dusted lightly on the fish, it helps the surface brown and gives a slightly golden crust.
The step that matters
Carefully lift the mackerel to a hot dish. Cooked mackerel is delicate and its flesh flakes easily, so lifting it gently with a wide spatula keeps the fish and stuffing intact.
