Zero commercial yeast has ever touched a single item in this Mesa bakery’s kitchen—everything rises with pure sourdough magic.
Proof Bread represents a beautiful rebellion against modern convenience, where husband-and-wife team Jon Przybyl and Amanda Abou-Eid have created one of the country’s most unique bakeries.
From their humble garage beginnings to crowdfunding over $100,000 from supporters worldwide, this micro-bakery has transformed a historic 1880s building into a sourdough sanctuary.
Every croissant, loaf, and pastry depends entirely on their beloved sourdough starter “Harriet,” creating naturally leavened perfection that has earned them a devoted following of 3,000 weekly customers and comparisons to San Francisco’s legendary bread scene.
Sourdough Mastery Beyond Compare
Zero Commercial Yeast Philosophy: Every single item in the bakery relies completely on natural fermentation through their sourdough starter Harriet, named after the mother from the ’90s sitcom Family Matters.
