Why it works: Sugar and egg are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 122,807 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

Ingredients
Directions
Clarify the liquor
Remove any scum from the liquor as it rises.
Boil the liquor gently for 6 to 7 hours until reduced by more than half.
Strain the liquor through a sieve into a basin and let it cool to set.
Remove all fat from the top of the cooled liquor and wash with warm water.
Make the jelly
In a saucepan, combine the strained liquor, sugar, and egg whites cold.
Heat the saucepan without stirring until it begins to warm.
Boil for about 10 minutes after it rises to a head.
Add a teacupful of cold water and boil for 5 more minutes.
Remove from heat, cover, and let sit for 1 hour near the fire.
Filter and strain
Prepare a jelly bag by dipping it in hot water and wringing it out dry.
Fasten the jelly bag to a stand or chair near the fire and place a basin underneath.
Pour the jelly into the bag and let it run through; repeat if not clear.

The flavor team
The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: 2-nonenal (fatty, green).
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Bind impurities into a foam that is skimmed off, leaving the jelly clear.
- Isinglass
- Gelatin-like protein that sets the liquor into a firm jelly as it cools.
- Loaf sugar
- Adds sweetness and body to the jelly.
The step that matters
Heating without stirring. Stirring while the egg whites and liquor heat breaks up the forming foam, so impurities mix back in and the jelly turns cloudy instead of clear.
