Why it works: Cream and vanilla are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 12,301 recipes. Both carry 2-nonanone, which smells fruity, floral. The science ↓
Boiled Frosting
Ingredients
Directions
In a saucepan, combine sugar, cream of tartar, and boiling water; stir over low heat until the sugar dissolves.
Boil gently without stirring until a soft ball forms when tested in cold water (238°F).
Gradually cool the syrup; slowly add it to the stiffly beaten egg white while continuing to beat until thickened; add flavoring.
Pour the frosting over the cake.
