Why it works: Flour and potato are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 5,355 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

What each ingredient does
- Flour
- Forms the bulk of the starter and provides starch and gluten for body.
- Liquid yeast
- Ferments the starter, producing gas that makes the mixture rise and turn light.
- Potato
- Adds starch and moisture that help the starter stay soft and feed the yeast.
The step that matters
Cooling to lukewarm before adding yeast. Boiling-hot liquid kills yeast cells, so the mixture must cool to lukewarm before the yeast goes in. Too hot and the starter will never rise.
