Why it works: Almond and flour are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Beaten to a stiff foam that gives the icing lightness and body.
- Powdered sugar
- Sweetens the icing and stiffens the whipped whites into a spreadable coating.
- Chopped almonds
- Add crunch and nutty flavor to the icing.
- Flour
- Provides the structure that holds the shaped dough together through baking.
The step that matters
Adding the powdered sugar. Sugar should be added gradually to stiff egg whites. Adding it too fast deflates the foam, so the icing loses its volume and will not spread or dry as intended.
