Dehydrating bread starter is a simple process that allows you to preserve it for future use. This method is ideal for storing excess starter or taking it with you when traveling.
Here's how to dehydrate your sourdough starter according to the provided steps:
Step-by-Step Dehydration Process
Dehydrating your starter involves spreading it thinly and drying it thoroughly until brittle.
Step 1: Prepare the Starter for Drying
The first crucial step is to spread your active or fed starter thinly.
- Spread the starter out on a silicone baking mat as thinly as possible. This ensures even drying and makes it easy to peel off once dry.
Why thinly? Spreading it thinly significantly speeds up the drying process and prevents mold growth.
Step 2: Dehydrate the Starter
Once spread, the starter needs to be dried using a dehydrator.
- Place the silicone mat with the spread starter into the dehydrator.
- Set the dehydrator temperature to 88 °F.
- Dry for 4 - 6 hours, or until it is completely dry and brittle.
Note: Drying time can vary depending on the thickness of the spread starter and your dehydrator model. Check periodically to ensure it's becoming crisp and easily breakable.
Dehydration Settings Summary
| Surface | Temperature | Time | Result |
|---|---|---|---|
| Silicone Baking Mat | 88 °F | 4 - 6 hours | Completely Dry |
Step 3: Prepare for Storage
After the starter is completely dry and brittle, it's ready for storage.
- Break the dried starter into small pieces.
- Alternatively, you can grind it into a powder. This creates a more uniform texture and takes up less space.
Storage Tip: Store the dried pieces or powder in an airtight container at room temperature. When stored properly, dehydrated starter can last for a very long time, often years.
Dehydrating your sourdough starter is an excellent way to create a backup or share it with others, allowing you to revive it later whenever you're ready to bake.
