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 ↓
Another Method for Making Yeast
Ingredients
Directions
Peel one large Irish potato.
Boil it until soft.
Rub it through a sieve.
Add an equal quantity of flour.
Make it sufficiently liquid with hop tea.
When it is a little warmer than new milk, add a gill of good yeast. Stir it well.
Keep it closely covered in a small pitcher.

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.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potato
- Provides starch and moisture that feed the yeast and give the starter body.
- Flour (in the method)
- Adds starch for the yeast to ferment and thickens the mixture into a batter-like starter.
- Yeast
- Ferments the sugars in the starter, producing carbon dioxide that makes bread rise.
The step that matters
Adding the yeast at the right temperature. Yeast works best when the liquid is only slightly warm, about the temperature of new milk. Liquid that is too hot can kill the yeast cells, while cool liquid slows fermentation.
