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 ↓
To Roast a Sturgeon
Ingredients
Directions
Prepare the fish
Soak the sturgeon in a mixture of salt and water for 6–8 hours.
Clean and scrape the sturgeon thoroughly.
Fix the sturgeon on a spit.
Roast
Baste the sturgeon with butter while roasting.
Dredge the fish occasionally with flour.
Mix the grated bread, sweet herbs, and parsley with a little butter and sprinkle the mixture over the fish.
Make the sauce
Combine water, anchovy, lemon peel, onion, sweet herbs, mace, cloves, black and white pepper, and horseradish in a saucepan.
Cover the saucepan and boil for 15 minutes.
Strain the mixture and return the strained liquid to the saucepan.
Add white wine, oysters with their liquor, walnut ketchup, and the butter rolled in flour.
Let the sauce simmer.
Pour the sauce over the roasted sturgeon before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sturgeon
- Is the main fish that is cooked and served, forming the body of the dish.
- Butter
- Bastes the fish during roasting, adding richness and helping the surface brown.
- Flour
- Dredged over the fish, helping form a light crust that browns during roasting.
- Oysters
- Add briny flavour and body to the sauce through their meat and liquor.
- White wine
- Adds acidity and depth to the sauce as it reduces with the strained broth.
- Bread
- Grated and mixed with herbs to form a crumb coating that crisps on the fish.
The step that matters
Let the sauce simmer. Once the oysters and butter rolled in flour are added, gentle simmering thickens the sauce and cooks the oysters without toughening them. Boiling hard can make the oysters rubbery and can cause the flour-thickened butter to separate or lump.
Swap the onion

Fit is the average pairing score against sturgeon, butter, flour, bread, parsley, anchovy, lemon. Candidates are from the same food group and used in at least 100 recipes.
