Can you use dried active yeast instead of fast action yeast?

Yes, dried active yeast can be used instead of fast-action yeast, but it will require some additional steps and may take a bit longer for the yeast to activate and ferment the dough. Here's how to use dried active yeast instead of fast-action yeast:

1. Hydration: Stir the dried active yeast into a small bowl of lukewarm water (105-115°F/40-45°C) along with a pinch of sugar. Let this mixture sit for 5-10 minutes until the yeast activates and starts to foam. This process is known as "proofing" the yeast, and it ensures the yeast is alive and ready to use.

2. Continue with the Recipe: Once the yeast is proofed, proceed with the rest of your baking recipe as you would with fast-action yeast. Add the activated yeast mixture to the rest of the ingredients, knead the dough, and let it rise according to the recipe's instructions.

It's important to note that dried active yeast may take longer to ferment the dough compared to fast-action yeast. Therefore, you may need to adjust the rising times indicated in the recipe accordingly. For example, if the recipe says to let the dough rise for 1 hour with fast-action yeast, you may want to increase the rising time to 1.5-2 hours with dried active yeast.

Also, dried active yeast is generally sold in larger packages than fast-action yeast. If you have leftover active dry yeast, be sure to store it properly in an airtight container in a cool, dry place. It can last for several months, but it's always a good idea to use it before the "expiration" date indicated on the package.
