What each ingredient does
- Kahlua
- Adds coffee sweetness and flavour, and a dense sugary body that layers well.
- Irish cream
- Adds creamy richness and a sweet dairy body that helps it float on denser layers.
- Rum
- Adds alcohol and a sharp, aromatic bite that lightens the sweetness of the other layers.
The step that matters
Pouring slowly over the back of a spoon. Layering works because liquids of different density separate when poured gently. Pouring fast or directly into the glass mixes the layers, since the denser liquid sinks and blends in before the lighter one can settle on top.
