Why it works: Cinnamon and clove match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,189 recipes. Both carry ethyl cinnamate, which smells sweet, balsamic. The science ↓
Lemon Jelly
Ingredients
Directions
Make the syrup
In a clean saucepan, combine water, lemon juice, lemon zest, sugar, cinnamon, gelatine, and cloves.
Stir over medium heat until gelatine is dissolved.
Clarify
Add crushed egg shells and beaten egg whites, whisk until boiling.
Remove scum that rises to the surface.
Prepare a cloth over a basin, pour boiling water through to heat it.
Pour the mixture through the cloth into the basin, repeating three times for clarity.
Set
When nearly cool, pour into a scalded and rinsed mold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Bind with impurities as they cook, lifting them to the surface so the jelly clears.
- Gelatine
- Sets the liquid into a firm, sliceable jelly as it cools.
- Lemon juice
- Provides the sharp acidity that defines the jelly's flavour.
- Sugar
- Adds sweetness and balances the sourness of the lemon juice.
The step that matters
Pouring through the cloth. Egg white and shell clarify the liquid by trapping cloudy particles as they coagulate and rise. Straining repeatedly, with the cloth pre-heated, keeps the jelly clear; pouring too quickly or letting it cool lets particles pass through and the liquid thicken unevenly.
