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
Prepare 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 gum 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 blue food coloring until well mixed.
Rest
Cover the finished gum paste with a cloth and let it rest in a damp place for 12 hours before use.

What each ingredient does
- Gum-dragon
- Provides the binding and elastic structure that lets the paste hold its shape.
- Icing sugar
- Adds sweetness and body, helping the paste firm up into a workable dough.
- Starch powder
- Absorbs moisture and keeps the kneaded paste from becoming sticky.
- Lemon juice
- Adds a little acidity that helps the gum hydrate and soften while grinding.
The step that matters
Resting the gum paste. Gum paste needs time to hydrate and relax evenly. Using it straight after kneading can leave it sticky, cracked, or hard to shape, so the damp resting period matters.
