The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Brown sugar
- Provides the sweetness and caramel flavor, and forms the syrup that sets the frosting.
- Egg whites
- Whipped into foam to give the frosting its light, airy structure.
The step that matters
Boil until the mixture spins a thread. Sugar syrup must reach the right concentration to set properly; too little cooking leaves the frosting soft and runny, while too much makes it hard and grainy. Watching for the thread stage gauges that concentration.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
