Why it works: Butter and sauce are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 15,338 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Fillets of Mackerel with Caper Sauce
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Remove the fillets from the mackerel and cut them in half.
Place the fillets on a buttered baking sheet and cover with buttered paper.
Bake and serve
Bake in a 400°F (200°C) oven until cooked.
Arrange the fillets in two rows, one leaning on the other.
Pour caper sauce over the fillets and mix in the liquor from the baking tin.

Shared aroma: ethanol (alcoholic, ethereal).
Butter and sauce barely smell alike, yet cooks put them together in 15,338 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mackerel fillets
- Form the main body of the dish, cooking into flaky, tender flesh in the oven.
- Butter
- Greases the baking sheet and paper so the fish does not stick, and adds richness.
- Caper sauce
- Adds a sharp, acidic contrast that cuts through the richness of the oily fish.
- Liquor from baking tin
- Carries cooking juices and flavour from the fish into the sauce, adding moisture.
The step that matters
Bake until cooked. Mackerel is oily and dries out or turns tough if overcooked, so checking for doneness in the oven matters for a moist, flaky result.
