Owner Katie Riehm shows doughnuts fresh from the oven Wednesday at her new Sweet Theory Baking Co., which opened Saturday at 1243 King St. in Riverside. The bakery offers “all natural and organic hand-crafted baked goods” that are egg-free, dairy-free, soy-free and peanut-free, with gluten-free options available. Sweet Theory offers Brooklyn egg cream sodas, coffee, tea and more. “Doughnuts have been the biggest seller,” she said. For information, visit Sweet Theory Baking Co. on Facebook.
