Jujube Paste

Ingredients

Directions

Make the paste

  1. Combine sugar, gum arabic, and water in a bowl.

  2. Flavor with essence of lemon and cochineal.

  3. Let the mixture sit in a warm place until the gum is dissolved.

  4. Cook the mixture until thick, testing in cold water; it should bend when cold.

Shape and set

  1. Pour into buttered pans, about ⅛ inch thick.

  2. 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.

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.
