Most weeks on the show, we help out home cooks who have had a kitchen fail. This week, the "fail" is coming from inside the test kitchen. Test Kitchen Editor Kendra Vaculin joins Chris to chat about the fraught recipe development process of Kendra's Foolproof Lemon Bars — which was caught on camera as part of our "How I Developed" video series. Chris and Kendra also share how the team works together in the Bon Appetit test kitchen to bring you recipes you'll be excited to cook at home.The Recipe: Foolproof Lemon BarsThe Video: "Developing These Perfect Lemon Bars Nearly Broke Me"
