Yeast packets, teaspoons and grams
One standard packet of active dry yeast is 7 g, which is 2¼ teaspoons — the amount most bread recipes call for. A teaspoon weighs about 3.1 g. Active dry yeast is traditionally proofed first: dissolve it in warm liquid around 110°F for 5–10 minutes until foamy, which also confirms it's alive.
It's interchangeable with instant yeast 1:1; active dry just works a little slower and benefits from that head start.
