Baking with Yeast, a free food & drink course on Tomo

Baking with Yeast

Take full control of your homemade breads, pizzas, and rolls. Learn how to keep yeast alive, judge dough rises by sight instead of the timer, and use cold fermentation to coax bakery-quality flavor from simple ingredients.

Like Duolingo, but for Baking with Yeast. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

A short one: 11 levels across 2 sections, about 22 minutes end to end, roughly 4 days at five minutes a day. It moves through Getting the Rise Right and Flavor and Dough Control. It starts from scratch.

Key ideas in Baking with Yeast

  • Water for activating yeast should feel lukewarm or comfortably warm like a baby's bath
  • Yeast is a living organism that dies when exposed to water above roughly 130°F (55°C)
  • Dead yeast cannot be revived by cooling the mixture down
  • Active dry yeast granules have a protective shell of dead yeast cells that must soften in liquid
  • Instant yeast is milled finely enough to hydrate and activate directly in dry flour
  • Yeast breaks down the natural starches present in flour into fermentable sugars
  • Added sugar acts as a quick booster to speed up rising, but is entirely optional for fermentation
  • Active yeast consumes sugars and releases carbon dioxide gas, producing a bubbly, frothy foam
  • A flat, murky bowl of water means the yeast is dead and must be discarded
  • Direct contact with concentrated salt draws water out of yeast cells through dehydration, killing or stunning them
  • Dispersing salt throughout the dry flour keeps it diluted enough that it regulates fermentation without destroying the yeast
  • Warm rooms speed up yeast fermentation, while cool rooms slow it down
  • Recipe rise times are only general guidelines based on ideal room temperatures
  • Dough volume and growth are the true signals of fermentation progress, not the clock
  • Dough that pushes back aggressively still has strong elasticity and needs more rise time
  • A dough that slowly recovers halfway holds enough gas to bake
