Does dried active yeast need to be frothy work in bread?

Here's why:

* Dried yeast is dormant. It's inactive until rehydrated with warm water.

* Froth indicates activation. The froth you see when rehydrating yeast is a sign that the yeast is alive and starting to ferment.

* Froth is not required for baking. Even if the yeast doesn't foam significantly, it can still be viable and work in your bread.

Here's what to do:

1. Rehydrate the yeast. Mix it with warm water (not hot!) according to package instructions.

2. Wait for signs of activity. Look for a slight increase in volume and a bubbly texture. This may take 5-10 minutes.

3. Proceed with your recipe. Even if the yeast hasn't frothed significantly, it can still work in your bread.

Note: If the yeast doesn't show any signs of activity after 10 minutes, it's likely dead. It's best to use fresh yeast for optimal results.
