Why it works: Potato and flour 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 ↓

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
- Potato
- Adds starch and body, helping the starter thicken and hold its structure.
- Flour (in the method)
- Provides starch that the yeast can feed on, giving the starter bulk.
- Yeast
- Ferments the mixture, producing gas that makes the starter bubble and rise.
The step that matters
Adding the yeast when the mixture is only a little warmer than new milk. Yeast is killed by excessive heat, while a cool mixture ferments slowly. Warm, not hot, liquid lets the yeast grow and start working steadily.
