Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Jelly, Festive
Ingredients
Directions
Prepare the mixture
Dissolve gelatin in 1 pint of cold water and stir thoroughly.
Sweeten to taste and add a few drops of vanilla.
Heat and clarify
In a saucepan, combine the gelatin mixture with ½ pint of cold water and the well-beaten egg white.
Bring to a boil, removing any scum that rises while stirring to prevent sticking.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Sets the liquid into a firm, wobbly gel as it cools.
- Egg white
- Coagulates as it heats, trapping impurities so the jelly clears.
- Sugar
- Adds sweetness to balance the flavour of the set jelly.
The step that matters
Bringing the mixture to a boil. Stir while heating so the egg white stays mixed in and does not stick to the pan. As it heats, the egg white and impurities rise as scum, which must be removed to keep the jelly clear.
