Why it works: Egg and sugar are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 122,807 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Directions for Frosting
Ingredients
Directions
Make the frosting
Break the egg into a flat dish and beat with a fork until stiff.
Add the powdered sugar and flavoring, or mix the sugar in before beating.
Ensure everything is thoroughly beaten before frosting the cake.
Prepare the cake
If the cake is rough or brown, dust with flour and remove loose particles with a cloth.
Spread and set
Spread the frosting smoothly with a knife and let it set in a warm place without browning.
If the frosting is too stiff, dip the knife in cold water to help spread it.
If the frosting dries too quickly, add a drop or two of hot water.
Add any decorations like raisins, nuts, or candies while the icing is still moist.
Make boiled frosting
For boiled frosting, combine 1 cup of sugar with water and boil without stirring until it ropes.
Beat the egg white, then stir in the boiled sugar and continue stirring until cool.

What each ingredient does
- Egg white
- Beaten until stiff, it traps air and gives the frosting its light, foamy structure.
- Powdered sugar
- Dissolves into the beaten white to add sweetness and body to the frosting.
- Sugar
- Boiled with water to a syrup that, stirred into the beaten white, sets into a glossy frosting.
The step that matters
Boiling the sugar without stirring. Stirring during boiling can cause sugar crystals to form, making the frosting grainy. Boiling until it ropes concentrates the syrup so it sets properly when cooled.
