Proof & Crumb is a small online shop for sourdough and artisan bread bakers — curated bannetons, lames, scrapers, couches and the kits that bring them together. We focus on practical tools and plain-spoken guides that help each tool earn its place.
We believe good bread is slow on purpose. The goal is not a drawer full of equipment; it is a small setup that fits the loaves you actually bake.
Who we are
Proof & Crumb is operated by Chaomao Supply Chain Management (Shenzhen) Co., Ltd. Orders are fulfilled by vetted overseas partner warehouses. Delivery takes longer than domestic fulfillment, so current estimates are published in our Shipping Policy, and tracking is provided after dispatch.
We are an online-only store with no walk-in retail location. Review our Returns Policy, compare our sourdough kits, or email hello@proofandcrumb.com.
