Bannetons are natural fiber baskets used to help the dough keep its shape while while proofing; MadeTerra actually has a super cool video showing how bannetons are made (scroll past the baking tools to The Maker). But you can find these pretty cheap on Amazon (link in picture) or in entire sets (see SD Sets).

Bread lames can be as beautiful as your bread! UFO lames (pictured) are small and circular, but sometimes razor blades are placed on longer handles. Blades are interchangeable, but I will probably still end up with a small collection someday...

The type of cloth used to line a banneton is a personal preference, but I've had the best results with simple flour-sack like cotton cloths like these ones from Amazon.. or just pick them up at Walmart. They're all the same. I like to use mine to strain yogurt, as well (;

The most expensive... and amazing thing you can have for baking sourdough. Of course, pizza stones and even normal baking sheets work quite well with the right setup (see the end of tip #9), but it's fantastic to experiment with cast iron, whether it's an affordable Lodge or the big brand names Le Creuset or STAUB Cocotte.

Okay, I just found this scraper set on Amazon (pictured) and I love that it includes both a rounded scraper AND a bench knife. This is great for getting all the dough off the sides of the bowl when mixing and cutting bits of dough as you bake. Plus it's got a ruler, that's cool!

Amazon makes it easy to get started with a lot of "sourdough starter sets" that come with a lot of fancy (unnecessary?) tools and are outrageously expensive. ^^This one I think sells at a good price point for what you get, but sometimes it's cheaper and better in terms of quality to buy things separately, especially with bannetons.

This is a MUST for any good SD kitchen! I can't say enough how much baking by weight has improved my bread; one thing I wish my scale had was a pull-out display like the one pictured here. This picture links to the cheapest pull-out display scale I could find on Amazon ($25), but I've made do with my cheap one for now (:

more coming soon...
