These Double Chocolate Sourdough Bagels combine the rich flavors of Dutch-processed cocoa and semi-sweet chocolate chips with the tangy depth of sourdough fermentation. Made with an active sourdough starter, brown sugar, and a hint of espresso powder for enhanced chocolate flavor, these bagels undergo a two-day process involving hydration, fermentation, boiling, and baking to achieve a chewy, flavorful crust and a tender crumb. Perfect for breakfast or an indulgent snack, these bagels offer a delightful twist on the classic sourdough with luscious chocolate notes throughout.
