Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Baked Skate
Ingredients
Directions
Make the sauce
Chop three onions.
Fry the onions to a light-brown colour in two ounces of butter.
Add half a pint of vinegar, pepper, and salt to the onions.
Allow the mixture to boil on the fire for five minutes.
Assemble
Put the skate in a baking dish.
Pour the sauce over the skate.
Add just enough water to reach the surface of the skate.
Strew a thick coating of bread-raspings on the fish.
Bake
Bake the skate for an hour and a half at rather moderate heat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Fat that carries the onion flavour and helps the onions brown lightly.
- Onions
- Provide sweetness and aroma as they fry and soften in the sauce.
- Vinegar
- Adds acidity that sharpens the sauce and balances the richness of the fish.
- Skate (in the method)
- The main fish, which becomes tender and flaky as it bakes in the sauce.
- Bread-raspings (in the method)
- Form a crisp, browned crust over the fish during baking.
The step that matters
Bake the skate for an hour and a half at rather moderate heat. Gentle, long baking lets the thick fish cook through and become tender without drying out, while the surrounding liquid keeps it moist.

Fit is the average pairing score against butter, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
