Why it works: Lemon and pepper 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 ↓
Sturgeon Ragoot
Ingredients
Directions
Prepare the fish
Wash and dry the sturgeon thoroughly, then cut it into slices, ½ to 1 inch thick.
Cover the slices with vinegar and let them soak for 5 to 6 minutes, then drain and dry.
Coat the fish lightly with flour seasoned with salt and pepper.
Brown and stew
Melt the butter or fat in a pan and fry the fish on both sides until lightly browned, then drain excess fat.
Place the fish in a stewpan, add the sherry (if using) and enough stock to barely cover the fish, then season with salt and pepper.
Cover and stew gently for about 1 hour.
Finish and serve
Transfer the fish to a hot dish, strain the gravy, and return it to the stewpan.
Season the gravy to taste, add the capers and a little lemon juice or vinegar, heat thoroughly, and pour over the fish.
Garnish with sliced lemon and serve.

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 stew, becoming tender during gentle stewing.
- Flour
- Light coating that helps the fish brown and thickens the gravy slightly.
- Butter or fat
- Carries the frying heat and gives the fish a golden, richly flavoured surface.
- White stock
- Liquid that cooks the fish gently and becomes the body of the gravy.
- Capers
- Add a sharp, briny note that cuts through the richness of the gravy.
The step that matters
Stewing gently with just enough stock. Gentle heat keeps the fish tender and intact, while a high boil would toughen the flesh and break the slices apart. Using only enough stock to barely cover concentrates the gravy's flavour.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
