Why it works: Sugar and lemon are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 53,532 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Jujube Paste
Ingredients
Directions
Make the paste
Combine sugar, gum arabic, and water in a bowl.
Flavor with essence of lemon and cochineal.
Let the mixture sit in a warm place until the gum is dissolved.
Cook the mixture until thick, testing in cold water; it should bend when cold.
Shape and set
Pour into buttered pans, about ⅛ inch thick.
Once cool, roll up into a scroll.

Shared aroma: 2-nonenal (fatty, green).
Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Provides sweetness and, once cooked, the body that sets the paste firm.
- Gum arabic
- Acts as a binder that thickens the mixture and gives the paste its chewy texture.
- Water
- Dissolves the sugar and gum so they can be cooked into a smooth mixture.
The step that matters
Cooking until thick and testing in cold water. Sugar syrup thickens as water evaporates and its concentration rises. Undercooking leaves the paste too soft to hold a shape, while overcooking makes it brittle. Testing a spoonful in cold water shows when it has reached the bendable stage.
