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 ↓
Almond Icing
Ingredients
Directions
Make the icing
Beat the egg whites until stiff.
Gradually add the confectioner's sugar, mixing until fully incorporated.
Stir in the grated or pounded almonds and rosewater.
Spread on the cake
Spread the icing thickly between or on top of the cake.
Place the frosting in the center of the cake, dip a knife in cold water, and spread from the center toward the edge.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to stiffness, they give the icing its light, airy structure.
- Confectioner's sugar
- Sweetens the icing and thickens it into a spreadable paste as it dissolves into the whites.
- Sweet almonds
- Provide body, nutty flavor, and richness to the icing.
- Rosewater
- Adds a delicate floral aroma to the almond icing.
The step that matters
Spread from the center toward the edge with a cold knife. Egg white icing is sticky and can tear or drag the cake crumb. Dipping the knife in cold water keeps the surface from grabbing, letting a smooth, even layer form.
