These dried flakes are your most important ingredient. They carry the wild yeast and beneficial bacteria that give real sourdough its rise and that distinct tang you won't get from a packet of commercial yeast.
Making a starter from scratch usually means a week or two of feeding flour twice a day and hoping it takes. Ours skips all that. The culture is already mature and stable, so you just rehydrate the flakes, give it a couple of feeds, and you'll have a strong, active starter ready for your first loaf in as little as 2 days.
One packet is all you need. A starter is alive, so once it's going you can keep it for years by feeding it.
What you'll want alongside it: this is the flakes packet only. If you're starting from scratch, the Complete Sourdough Starter Kit is the easiest way in, with the starter plus flour, a jar, and all the tools to bake your first loaf. Already have the gear and just need somewhere to keep your starter? Add a Starter Jar, or grab the Jar + Flakes bundle and save.

I never knew ‘discard’ was so useful ‼️
My daughter feeds it to her cooks 😫

Thank you 💖
This is the best book about sourdough I have ever read. So much info and all the answers I needed at the time. If the book is on the kitchen bench then my husband knows in the next day or two, he will be eating yummy homemade sourdough. Thank you.
What wonderful praise, Elizabeth! 🥰 We’re thrilled the Cookbook has answered your questions, and we love that seeing it on the bench gives your husband something delicious to look forward to! 🍞

Hi since ive started using your knead flour, ive found my loafs to be amazing, im still learning but I am enjoying the whole sourdough process. I recently made a loaf one using your heavy duty bread tin and it turned out great for my first time 😄💓
What a fantastic first bake in your Heavy Duty Bread Tin, Michelle! We’re thrilled the flour is helping you create amazing loaves while you enjoy learning the sourdough process. Keep having fun with every new bake! 😄💓

Brought the dried starter to help start my sourdough journey.
I’ve managed a few loaves already, so this starter makes it a lot easier to start
