Karen Morgan's now-ex-husband, Tim Morgan, trained at La Varenne, the legendary cooking school founded by Anne Willan in Paris, France. Karen trained in pastry with Tim. In 2002, she was diagnosed with celiac disease and struggled to find desserts she could bake or consume. She began devising her own recipes. After cooking in France for four months in 2006, she started her food blog, The Art of Gluten-Free Cooking. Karen opened Blackbird Bakery, a custom gluten-free bake shop that caters special events, in 2008.
