Starter fed, family fed, iced coffee secured. The Cool Mom Who Bakes Sourdough glass sipper is made for moms whose kitchens always seem to have a loaf proofing somewhere. Keep your favorite cold drink nearby through stretch and folds, shaping, scoring and early-morning bakes. A fun gift for sourdough moms, bread bakers and home bakers who proudly juggle motherhood, fermentation schedules and the never-ending question of when the starter was last fed.
