Proof Bread creates artisan breads -- both new and inventive rotating speciality loaves, such as blueberry thyme sourdough, and classics: sourdough, sandwich bread, baguettes and more. Pastries include almond and chocolate croissants, pinwheels and streusel, among other rotating items. Everything is hand-mixed and naturally leavened. Proof can be purchased at 5 local farmers markets: Uptown Farmers Market, Agritopia Farm Market, Gilbert Farmers Market, Downtown Phoenix Farmers Market, and Tempe Farmers Market.
