Why would you use sourdough discard?

Many people wonder why they would use something called “discard”.

But this unique ingredient has a lot of uses and benefits!

Emergency backup in case your starter gets contaminated or worse

Killing a sourdough starter is difficult because they are robust and resilient. However, mold in the air or a contaminated jar or spoon can cause issues.

A starter in poor health, one that isn’t refreshed (discard and feed) regularly, which means the majority of the waste is removed and the remainder is fed, can be more susceptible to problems.

And even worse… some well intentioned person in your household might think it is something that needs washing out. This has happened to many of my students.

Or I’ve also had students accidentally break their glass jar of starter.

In any of this situations, some old discard reserved in the fridge can be made into a healthy starter again.
