Fresh yeast is a living organism that begins fermenting when combined with flour or sugar. As it ferments, it releases carbon dioxide, which makes the dough rise.

To prepare fresh yeast:

1. Place it in a bowl with a small amount of sugar.
2. Mash it gently with the back of a spoon.
3. Within about 30 seconds, it will dissolve into a smooth liquid.
4. Add water as directed in your recipe.

Substituting Yeast

If a recipe calls for fresh yeast, you can substitute:

• Half the quantity as active dry yeast
• One quarter of the quantity as instant yeast

For example, if the recipe uses 30 g fresh yeast, you can use 15 g active dry yeast or 7 g instant yeast.
