Why it works: Lemon and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
To Bake Fish
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
Season the fish with salt and pepper, rubbing it inside and out.
Place the fish on a large dish with sliced onions.
Sprinkle lemon juice over the fish.
Cover the fish and set aside for 1 hour.
Bake and serve
Lay the fish in a baking pan with 4 slices of pork underneath and 3 slices on top.
Pour melted butter over the fish.
Bake at 400°F (200°C) for 45 minutes.
Serve hot, garnished with lemon quarters and parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the dish, cooking through in the oven to become flaky and tender.
- Pork slices
- Release fat as they bake, basting the fish and adding savory flavor.
- Onions
- Add sweetness and aroma as they soften and mingle with the juices under the fish.
- Lemon juice
- Adds acidity that brightens the flavor and begins to firm the fish surface.
- Melted butter
- Adds fat that promotes richness and gentle browning on the surface.
