Why it works: Sugar and rum are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 2,908 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓

What each ingredient does
- Egg yolks
- Provide richness and structure, helping the frosting thicken and hold its shape when beaten.
- Sugar
- Adds sweetness and, when beaten with the yolks, helps build a stiff, stable texture.
- Old jamaica rum
- Adds aroma and flavour to the frosting.
The step that matters
Judging the stiffness before adding more sugar. Beaten egg yolks and sugar only firm up gradually as the sugar dissolves and air is worked in. Adding sugar too early or too quickly can leave the mixture loose, while the right stiffness is needed for the frosting to hold its place on the cake.
