Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Fresh Sturgeon Steak
Ingredients
Directions
Prepare the fish
Soak the sturgeon slice in hot water for 5 minutes.
Drain and place in a bowl.
Add vinegar, melted butter, salt, black pepper, and lemon juice.
Let marinate for 6 hours, turning occasionally.
Drain and dry on a napkin.
Fry and serve
Dip in egg, then roll in bread crumbs.
Fry in very hot fat until cooked.
In a bowl, beat the egg yolks and mix in French mustard.
Gradually add half of the marinated mixture to create a smooth sauce.
Serve the sauce with the fish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sturgeon
- Is the main protein, cooked through by frying after marinating.
- Vinegar
- Acidity in the marinade that tenderises the fish and brightens its flavour.
- Egg yolks
- Emulsify with the butter-and-marinade mixture to thicken the smooth sauce.
- Butter
- Adds richness and fat to the marinade and sauce.
- Bread crumbs
- Form a crisp, golden browned coating when fried.
The step that matters
Dry the fish before frying. Surface moisture from the marinade and water soak turns to steam in hot fat, which prevents a crisp, browned coating and can cause the crumbs to fall off or splatter. Drying on a napkin helps the coating adhere and brown.
Swap the mustard
How well each one fits the dish's main ingredients (sturgeon, vinegar, butter, pepper, lemon, egg, bread):
- Capsicumfits better
- Shallotfits better
- Cucumberfits about as well
- Mustardthe original
Fit is the average pairing score against sturgeon, vinegar, butter, pepper, lemon, egg, bread. Candidates are from the same food group and used in at least 100 recipes.
