Hi, I'm Roselle.
I've baked 2,973+ loaves in a 27×30" workspace with 7 people in my house.
If I can make sourdough work in that chaos, you can make it work anywhere.
This starter isn't some 100-year-old heirloom from Etsy. It's the culture I use every single day. The one that's behind every loaf you see on my Instagram. The one that's never failed me.
When you buy this starter, you're getting the exact same culture I'm using in my kitchen right now.
