About Active Dry Yeast

What it is

Active dry yeast turns flour and water into bread. It's alive but dormant — warm water and a little sugar wake it up. The foundation of nearly every yeasted baked good.

Key thing to know about Active Dry Yeast

Water too hot (above 115°F) kills the yeast. Salt directly on yeast kills it — always blend flour first. For pita: a soft dough that proofs once, rolls thin, and bakes hot (500°F+) puffs into pockets.

1 packet (2.25 tsp / 7g) per loaf; proof in warm water (105-110°F) with a pinch of sugar for 5-10 min until foamy; mix into flour separately from salt

These are the most common uses for Active Dry Yeast. Each card explains what to do, why it works, and what to notice.

How to use Active Dry Yeast for making bread

Proof 2 1/4 teaspoons (1 packet) in 1/4 cup of warm water (105–110°F) with a pinch of sugar for 5–10 minutes until foamy.

Why it works for making bread

Active dry yeast is alive but dormant — warm water and a little food (sugar or flour) wake it up. If it doesn't foam after 10 minutes, the water was too hot, or the yeast was old. Use foamy water in your dough.
