Why it works: Flour and molasses are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 10,429 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
To Make Yeast
Ingredients
Directions
Make the starter
Boil 2 cups of water until reduced by half.
Strain the water through a sieve and return it to the pot.
Mix flour with cold water to achieve a thick molasses consistency.
Add the flour mixture to the hot water and boil for a few minutes.
Remove from heat and let cool until lukewarm.
Add yeast to the mixture and let it rise.
Rest overnight
Transfer the yeast to a stone jar, cover it, and let it sit overnight.

The flavor team
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
- Flour
- Thickens the boiled water into a starter with body that feeds the yeast.
- Yeast
- Ferments the mixture, producing gas that makes the starter rise and bubble.
The step that matters
Cooling to lukewarm before adding yeast. Yeast is killed by high heat, so the mixture must cool to lukewarm before it is added. Adding yeast too early can stop fermentation before it starts.
