Active dry, instant and fresh yeast

Our rule of thumb by weight: 1 g instant yeast = 1.25 g active dry = 3 g fresh yeast. A packet of dry yeast is 7 g (¼ oz, 2 ¼ teaspoons).

Using each kind

  1. Active dry: dissolve it in warm water (about 105 to 110°F) with a pinch of sugar; it should foam in 5 to 10 minutes.
  2. Instant (rapid-rise): mix it straight into the flour. Many bakers swap it one for one with active dry; ours uses a little less, and the dough rises a bit faster.
  3. Fresh (cake) yeast: crumble it into lukewarm liquid. A cake is about 0.6 oz (17 g); it keeps about 2 weeks in the fridge.
  4. These are our own ratios, not a lab standard: brands differ and dough temperature matters more, so watch the rise, not the clock.
