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 Pickling Sturgeon
Ingredients
Directions
Prepare the fish
Cut the sturgeon into chunks the same length as their thickness.
Rub the fish with coarse sea salt and let it drain for several hours.
Tie each piece of fish with thread.
Cook and make the jelly
Boil the fish in equal parts vinegar and water with a generous amount of black pepper until fully cooked.
Skim off the oil and let the fish cool to remove excess fat.
Melt the jelly by heating the pot.
Remove the fish from the pot and wipe the fish dry.
Add more vinegar and black pepper.
Boil the jelly until strong, optionally adding isinglass or fish parts for strength.
Pack and seal
Pack the sturgeon into small casks.
Pour the hot jelly over the fish in the casks.
Once cooled, pour clarified melted mutton fat over the fish.
Seal the cask.
Pierce a hole in the head of the cask.
Add more fat.
Seal the cask once frozen.

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 that is cooked and preserved in the jelly and fat.
- Vinegar
- Provides acidity that helps preserve the fish and sharpens its flavour.
- Fish skins, carcasses, or bones
- Release gelatin that helps the jelly set firm and strong.
- Clarified mutton fat
- Forms a sealing layer over the fish that limits contact with air.
- Black pepper
- Adds aromatic heat that flavours the fish and the jelly.
The step that matters
Boil the jelly until strong. Gelatin from fish skins, bones or isinglass sets the jelly firmly only when it is reduced enough. Too little boiling leaves a weak jelly that will not hold the fish or seal the cask well.
“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.
