things people ask

• How many yeast packets are in a tablespoon?
  A level tablespoon of dry yeast is about 9 grams, which is just over one and a quarter standard 7-gram packets, or about four-fifths of an 11-gram sachet. If you're measuring from a jar of bulk instant yeast, one tablespoon is enough for roughly 900 grams to 1.8 kilograms of flour at typical 0.5-1 percent dosing — plenty for a double batch of pizza dough or two large loaves.
• Can I substitute fresh yeast for a tablespoon of dry?
  Yes, but expect about 27 grams of fresh cake yeast — three times the dry weight — for the same leavening power. Crumble it directly into lukewarm liquid before mixing rather than measuring by tablespoon, since fresh yeast packs unevenly. The flavor will be slightly milder and the proof a touch faster, which suits enriched doughs like brioche and stollen.
• Why does my tablespoon of yeast weigh different on different days?
  Yeast granules absorb humidity. A tablespoon scooped from a freshly opened jar in dry winter air can read 9 grams clean, while the same scoop from a jar that's been open in a humid kitchen might tip 10-11 grams. For long-fermented doughs the difference matters — over-yeasted dough ferments out before the gluten and flavor develop. Store the jar sealed in the fridge or freezer to keep it consistent.
