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

Hops
Adds bitterness and aroma to the liquid.
Flour
Supplies starch that the yeast can ferment, giving the mixture body.
Yeast
Ferments sugars and produces carbon dioxide, which makes the mixture rise.

The step that matters

Stir in the yeast. Yeast is a living organism that high heat kills, so the mixture must be cool before the yeast goes in. Only then can it ferment and rise.
