As a follow up to my post on bread, I just wanted to point out Dan Lepard’s excellent video of reviving a lump of frozen sourdough into an active starter:

Awakening the frozen sourdough

Great to see it in action. For anyone wondering, sourdough is simply bread leavened with yeasts from the air and the flour, raised into a starter that you keep alive, instead of by adding dried or fresh yeast. Freezing this mixture is a great way to be able to make sourdough without having to do it every week to keep the starter active. I have some rye starter in my fridge right now, and I’m going to have a go at freezing some this week – will let you know how it goes.
