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 and bake
Fillet the fish, wash, and dry them.
Place the fillets on a baking sheet and sprinkle with lemon juice.
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.
Finish and serve
Carefully transfer the fillets to a serving dish.
Pour the cheese sauce over the fillets, 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
- Fish fillets (in the method)
- Provide the main body of the dish, which cooks gently to a flaky texture.
- Butter
- Adds fat and moisture, keeping the fish from drying out while it bakes.
- Lemon juice
- Adds acidity that brightens the mild flavour of the fish.
- Cheese sauce
- Adds creamy richness and moisture over the fillets.
- Dry cheese
- Melts and browns on top, adding savoury flavour and a golden crust.
The step that matters
Browning the cheese topping. Dry cheese sprinkled on top can burn quickly under a hot grill, turning bitter. Watch it closely so it turns golden and melted rather than dark, because browning depends on sugars and proteins reacting at high heat.
Swap the lemon
How well each one fits the dish's main ingredients (cheese, sauce, butter, pepper):
- Plumfits about as well
- Mangofits about as well

- Lemonthe original
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.
