Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Fillets of Fish and Cheese 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 the fish
Fillet the fish, wash, and dry them.
Place the fillets on a baking sheet and sprinkle with lemon juice.
Bake and finish
Dot with small pieces of butter, cover with buttered paper, and bake at 400°F (200°C) for 20 to 30 minutes, depending on thickness.
Carefully transfer to a serving dish and pour over the cheese sauce seasoned with salt, pepper, and parsley.
Sprinkle with dry cheese and brown under the grill or in front of the fire.
Serve hot.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Sauce and butter 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
- Mullet or bream
- Forms the flaky, delicate main body of the dish once baked.
- Cheese sauce
- Adds moisture and rich, savoury flavour over the cooked fillets.
- Dry cheese
- Melts and browns on top, adding a golden crust and sharper flavour.
- Butter
- Adds fat that keeps the fish moist and carries flavour during baking.
The step that matters
Browning the top under the grill. Fish and cheese can dry out or scorch quickly under high heat. Watching closely lets the dry cheese melt and brown without overcooking the fillets beneath.
Swap the lemon
How well each one fits the dish's main ingredients (cheese, sauce, butter, pepper):

Fit is the average pairing score against cheese, sauce, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
