Why measuring active dry yeast by cup goes wrong
Active dry yeast and instant yeast both come from the same organism in slightly different processing. Active dry needs to be bloomed in warm water (105–115 °F) before mixing; instant yeast can be added directly to the dry ingredients. A standard packet is 2 1/4 teaspoons or 7 grams.
Practical tips for working with active dry yeast
Yeast measured by the cup is impractical — measure by the teaspoon or by the gram. To test an older packet, dissolve a teaspoon in 1/4 cup warm water with a pinch of sugar; in 5 minutes it should be foamy and smell yeasty. If nothing happens, the yeast is dead and the bread won't rise.
Note from this ingredient's record: Sold by the gram for a reason. A standard packet is 2 1/4 teaspoons or 7 g — enough to raise 4 cups of flour.
