Why it works: Fish and mutton work together. They rank in the top 13% of all ingredient pairs, and cooks put them together in 121 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Cossack Method of Piclding Sturgeon
Ingredients
Directions
Prepare the fish
Cut the small sturgeon into chunks 4 to 5 inches long.
Rub the chunks with coarse sea salt and let drain for several hours.
Tie each piece with thread.
Boil the pieces in equal parts vinegar and water with black pepper until cooked.
Skim off the oil and let the fish cool to remove fat.
Wipe the fish dry.
Make the jelly
Melt the jelly in the pot.
Add more vinegar and black pepper, and boil the jelly until strong, adding isinglass or fish parts if needed.
Pack and seal
Pack the sturgeon in small casks and pour over the hot jelly.
Once cooled, pour clarified melted mutton fat over the fish and seal the cask.
Pierce a hole in the head and add more fat, then seal when frozen.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Small sturgeon
- Forms the main body of the preserve, providing the flesh that is cooked and packed.
- Vinegar
- Provides acidity that helps preserve the fish and sharpens its flavour.
- Isinglass or fish skins
- Supplies gelatin that helps the cooking liquid set into a firm jelly.
- Clarified melted mutton fat
- Forms a sealing layer over the fish that limits contact with air.
The step that matters
Boiling the jelly until strong. The jelly must reach enough gelatin concentration to set firmly when cooled. Adding isinglass or fish parts and boiling down the liquid concentrates the gelatin, so a weak jelly will fail to set and leave the fish poorly protected.
