How Do You Defrost Sourdough Starter?
It’s when it comes to defrosting your sourdough starter is when the work starts. You need the yeast to become active again before using, so it will take a while before you can start baking.
- Place into the Fridge
First, you need to take it out of the freezer and pop it into the fridge. It’s important to allow it plenty of time to thaw out fully and slowly, so don’t try and speed this process up.
- Discard Half
Throw half of the sourdough starter away and put the rest into the fridge.
As the sourdough starter thaws, you will need to start feeding it. Yeast is fairly hungry, especially when coming out of hibernation, so you need to restart a regular feeding schedule similar to the one you will have used to create the starter. On day one, as it thaws, feed it either once or twice that day.
- Continue Feeding
After the first day, feed it once or twice every day until you see those bubbling signs of it becoming active again.
- Give it Time
Allow the starter to grow, and when this looks stable, your sourdough starter is ready to use. This could take a few days from taking it out of the freezer.
