Why it works: Lemon and sugar 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 ↓
Lemon Frosting
Ingredients
Directions
Make the frosting

Add the finely sifted powdered sugar until the mixture is thick enough to spread.
Finish the cake

Spread and smooth the frosting with a thin-bladed knife dipped in water.

Shared aroma: 2-nonenal (fatty, green).
Lemon and sugar 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
- Lemon juice
- Provides the acidity and bright lemon flavor that defines the frosting.
- Powdered sugar
- Dissolves into the juice to thicken it and provides sweetness for a spreadable frosting.
The step that matters
Adding the powdered sugar. Sugar must be added gradually and sifted so it dissolves smoothly. Adding too much at once or leaving lumps makes the frosting stiff, grainy, or uneven, and it becomes hard to spread.
