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 wish to thank Ariane for the support and advise recently given to me. It was very helpful.
Quick turn around and safe delivery …always good
I followed the instructions but for some reason it just wouldn't grow. Although after around 4 days it grew mould so I had to throw it k out. Disheartened now 😕
