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 ↓
Baked Mackerel, or Whitings
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 the fish
Open the fish just enough to empty and clean them thoroughly.
Wash and dry the fish, then wrap them in a soft cloth for a while.
Replace the roe inside the fish and place them in a baking dish.
Season and bake
Add wine, chili vinegar, salt, cayenne, and blend butter with flour for each fish.
Arrange the fish with heads and tails towards each other, backs down.
Cover with buttered paper and press down.
Bake in a gentle oven at 300°F (150°C) for 20 minutes.
Remove the paper and serve the fish with the sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mackerel or whitings
- The fish is the main substance of the dish, cooked gently until flaky and moist.
- Butter
- Blended with flour, it enriches the sauce and adds richness and moisture to the fish.
- Flour
- Mixed with butter, it thickens the liquids in the baking dish into a light sauce.
- Wine
- Adds moisture and a mild acidity that contributes to the flavor of the sauce.
- Chili vinegar
- Adds sharp acidity and heat that brightens the rich butter sauce.
The step that matters
Cover with buttered paper and press down. Covering the fish traps steam so it cooks gently and stays moist, while pressing keeps it in contact with the liquid for even cooking. Buttered paper prevents sticking.
