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 ↓
Baked 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 the fish
Preheat the oven to 400°F (200°C).
Make an 'S' shape on the sides of the cleaned fish.
Rub the fish inside and out with pepper and salt.
Butter a stewpan. Add the chopped onion and water to the pan.
Place the fish in the pan. Add lumps of butter on top of the fish.
Bake and baste
Bake the fish for 20 minutes.
Baste the fish frequently while baking.
Carefully lift the fish out of the pan. Place the fish on a serving dish.
Make the gravy and serve
In the same pan, add oyster water, lemon juice, mushrooms, parsley, thyme, marjoram, allspice, garlic, cayenne, and additional salt and pepper.
Mix the mixture thoroughly over the stove. Add butter if the gravy sticks.
Pour the gravy over the fish.
Garnish with whole mushrooms and lemon slices on croutons or dried toast.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Whole fish
- Forms the main body of the dish, cooked gently in the pan until flaky.
- Butter
- Adds richness and moisture, and helps keep the fish from drying out while baking.
- Onion
- Adds savoury sweetness and aroma to the liquid around the fish.
- Oyster water
- Supplies salty, briny flavour to the gravy.
- Lemon juice
- Adds acidity that brightens the rich gravy.
- Mushrooms
- Add earthy flavour and body to the gravy.
The step that matters
Adding butter to the gravy. If the gravy sticks or scorches, its flavour turns bitter and burnt. Adding a little butter and stirring thoroughly over the stove keeps the sauce smooth and evenly heated.
Swap the onion
How well each one fits the dish's main ingredients (fish, pepper, butter, oyster, lemon, mushroom, parsley):
- Shallotfits better
- Asparagusfits better

- Onionthe original
Fit is the average pairing score against fish, pepper, butter, oyster, lemon, mushroom, parsley. Candidates are from the same food group and used in at least 100 recipes.
