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 Marinade
Ingredients
Directions
Prepare the fish
Soak the sturgeon slice in hot water for 5 minutes, then drain.
In a bowl, combine vinegar, melted butter, salt, black pepper, and lemon juice.
Add the sturgeon to the marinade and let it sit for 6 hours, turning occasionally.
Drain the sturgeon and dry it on a napkin.
Coat and fry
Dip the sturgeon in beaten egg, then roll it in bread crumbs.
Fry the sturgeon in very hot fat until cooked through.
Make the sauce and serve
In a bowl, beat the yolks of 2 raw eggs with French mustard.
Gradually add half of the marinade to the egg mixture to create a smooth sauce.
Serve the sauce with the fried sturgeon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sturgeon
- Firm, thick fish that holds its shape through soaking, marinating and frying.
- Eggs
- Bind the bread crumb coating to the fish and, as yolks, emulsify the sauce.
- Bread crumbs
- Form a crisp, golden browned crust when fried in hot fat.
- Vinegar
- Acidity that tenderizes the fish surface and sharpens the flavor of the marinade.
- Melted butter
- Adds fat and richness to the marinade, carrying flavor into the fish.
- French mustard
- Adds sharp flavor and helps emulsify the egg yolks into a smooth sauce.
The step that matters
Gradually add half of the marinade to the egg mixture. Adding the acidic liquid slowly while whisking lets the egg yolks emulsify it into a smooth sauce. Pouring it in all at once can cause the sauce to split or curdle.
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.
