Why it works: Onion and potato are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Esturgeon Roti
Ingredients
Directions
Prepare the fish
Remove the skin from the sturgeon and lard it well.
Tie the sturgeon with cooking string and roast it.
Make the basting liquid
In a stewpan, combine the sliced onion, carrot, dark stock, salt, pepper, and sherry or marsala.
Heat on a brisk fire until it boils, then strain the mixture.
Roast and serve
Baste the sturgeon frequently with the strained liquid while roasting.
Once the fish is browned, dish it up and pour the drippings over it.
Serve with slightly browned potatoes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sturgeon
- Forms the main body of the dish, cooked whole and tied to hold its shape.
- Dark stock
- Provides savoury depth to the basting liquid and drippings.
- Sherry or marsala
- Adds acidity and sweetness to the basting liquid, building flavour as it reduces.
- Butter
- Adds fat and richness, helping the fish brown and stay moist while basting.
The step that matters
Basting the sturgeon frequently. Lean fish dries out quickly over heat. Repeated basting with the strained liquid keeps the surface moist and helps it take on an even brown colour.
Swap the onion
How well each one fits the dish's main ingredients (sturgeon, pepper, carrot, sherry, butter, potato):

- Leekfits about as well
Fit is the average pairing score against sturgeon, pepper, carrot, sherry, butter, potato. Candidates are from the same food group and used in at least 100 recipes.
