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 ↓
White Glace Icing
Ingredients
Directions
Make the icing
Sift the icing sugar through a fine sieve into a clean saucepan.
Mix in the lemon juice and enough water to achieve a very thick sauce consistency.
Warm the mixture over low heat just to take the chill off.
Finish
Pour the icing over the cake immediately.

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
- Icing sugar
- Provides sweetness and the bulk that forms the glaze.
- Lemon juice
- Adds acidity that brightens the sweetness of the icing.
The step that matters
Warm only gently over low heat. Icing sugar can scorch or turn grainy and dull if overheated. Warming just enough to take the chill off keeps the glaze smooth and pourable.
