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
- Fine flour
- Thickens the water into a body that holds the yeast and feeds it.
- Brown sugar
- Provides sugar that the yeast consumes, driving fermentation and adding sweetness.
- Fresh yeast
- Ferments the sugars and produces the gas and flavour that make the starter active.
The step that matters
Let cool nearly to room temperature before adding yeast. Yeast is killed or weakened by excessive heat, so the mixture must be cool enough that it will not harm the cells, yet still warm enough to stay active.
