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 ↓
To Prepare Gum Paste
Ingredients
Directions
Soften the gum
Soak the gum-dragon in cold water in a covered container for 24 hours.
Wring the soaked gum through a strong cloth.
Make the paste
Place the gum on a marble slab and grind it with your fist, adding lemon juice gradually.
Incorporate the icing sugar gradually until fully absorbed.
Knead in the starch powder and a few drops of blue food coloring for whiteness.
Cover the finished gum paste with a cloth and let it rest in a damp place for 12 hours before use.

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
- Gum-dragon
- Forms the elastic base that gives the paste its structure once softened and worked.
- Icing sugar
- Adds sweetness and stiffens the paste as it is absorbed and kneaded in.
- Starch powder
- Dries the paste and reduces stickiness so it can be handled and shaped.
- Lemon juice
- Adds a little acidity that helps the gum soften and break down during grinding.
The step that matters
Grinding the gum with lemon juice. Gum-dragon hydrates into a stringy mass that must be worked gradually; adding liquid or sugar too fast leaves lumps and uneven texture that resist kneading.
