Why it works: Rye and flour match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and cooks put them together in 1,320 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
An Easy Method of Making Yeast
Ingredients
Directions
Stir rye flour and cold water until thick.
Pour in boiling water while stirring until thin like store-bought yeast.
Let it cool, then add ½ pint of lively yeast.
When it bubbles well, bottle it, but do not cork tightly if very lively.

What each ingredient does
- Rye flour
- Supplies starch and nutrients that the wild yeast feeds on as the starter builds.
- Cold water
- Hydrates the flour so it forms a thick mixture before the boiling water is added.
- Lively yeast
- Provides active yeast cells that ferment the starter and make it bubble.
The step that matters
Pour in boiling water while stirring. Boiling water gelatinizes the flour's starch, thinning the mixture. Adding it slowly while stirring prevents hot pockets and lumps, so the starch cooks evenly.
