Why it works: Parsley and lemon 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 ↓
Baked Fish
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Rub the fish inside and out with salt and pepper.
Place the fish in a dish with sliced onions and sprinkle with lemon juice.
Cover 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 and bake at 350°F (175°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
- Pork slices
- Fat from the slices bastes the fish and adds savory flavor as they cook.
- Onions
- Sliced onions add aroma and mild sweetness as they soften and release moisture.
- Lemon juice
- Acidity brightens the flavor and begins to firm the fish surface.
- Butter
- Fat adds richness and helps the fish surface brown gently in the oven.
The step that matters
Resting the fish in salt, pepper and lemon for 1 hour. Salt draws moisture out of the fish and then it is reabsorbed, seasoning the flesh more deeply. Acid from lemon juice starts to firm the proteins at the surface. Covering keeps the fish from drying while it rests.

- Onionthe original
Fit is the average pairing score against fish, pork, butter, pepper, parsley, lemon. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
