Why it works: Onion and tomato are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 20,633 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Halibut--turkish Style
Ingredients
Directions
Prepare the pan
Place two or three slices of onion on the bottom of a baking pan.
Place a cutlet of halibut on the onion.
Put a tablespoonful of butter, cut into small bits, over the top of the fish.
Add the vegetables
Cut three skinned tomatoes into quarters.
Slice a sweet green pepper into ribbons.
Put the tomatoes and pepper on the fish.
Bake and serve
Put the pan on the shelf of the oven to cook the vegetables first, without letting them discolor or change shape.
Remove the pan to the bottom of the oven, baste it well, and finish cooking.
When done, place the fish carefully on a hot dish.
Pour the juice from the pan over the fish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Halibut (in the method)
- Forms the main body of the dish and cooks gently in the pan juices.
- Butter
- Adds fat and moisture that bastes the fish as it bakes.
- Tomatoes
- Release juice that moistens the fish and adds gentle acidity.
- Onion
- Sits under the fish, adding aroma and flavour to the pan juices.
The step that matters
Baking the vegetables first on the upper shelf. Starting high in the oven lets the vegetables cook without discoloring or losing their shape. Moving the pan lower afterward finishes the fish gently, so it stays moist rather than drying out.
