They absolutely don’t require bespoke flours and mixes. Yeah, they sell those, but your standard bread recipe will work just fine. I routinely make this amazing loaf of bread using a slightly altered version of a recipe for sub rolls from Ethan Chlebowski It works freaking perfectly. Just about any bread recipe works great. The biggest downside to the break maker is the holes in the load from the paddles, and that’s sorted by just setting your machine manually to knead, and then remove the paddles before rising, and then setting bake time manually. Sure, slightly more work that one button, but if you don’t mind paddle holes, just say fuck it and do a one button loaf instead.
