A week away, a month away, or a whole season: here is how to rest your sourdough starter in the fridge or freezer, and how to wake it back up.

A week away, a month away, or a whole season: here is how to rest your sourdough starter in the fridge or freezer, and how to wake it back up.

Now that you’ve built your own starter, gotten one from a friend, or bought one from a fellow baker, keeping it alive is the part nobody warns you about enough. I keep mine in the fridge, feed it exactly what I need for whatever I’m baking, and I have never once thrown a spoonful of it in the trash. Here’s exactly how I maintain mine, and how I bring it back when it’s gone further than I meant to let it.

Sometimes you end up with more active starter than you actually need. Maybe you planned a big bake and scaled it back, or maybe you’re about to travel for work and won’t be near your kitchen for weeks. Either way, feeding a starter you’re not using, or trusting it to just sit forgotten in the fridge, isn’t your only option. Dehydrating it is, and it’s the method I reach for whenever I know I won’t be baking again soon.
