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 dissolves.
Cook the mixture until thick, testing in cold water; it should bend when cold.
Shape and finish
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 thick, the firm body of the paste.
- Gum arabic
- Dissolves into the water to bind the mixture and give it a chewy, elastic texture.
- Water
- Dissolves the sugar and gum so the mixture can be cooked down and set.
The step that matters
Cooking until thick. Sugar syrup thickens as water evaporates and concentrates. Undercooking leaves the paste too soft to hold its shape, while overcooking makes it brittle. The cold-water bend test checks the texture before pouring.
