Everyone has a disaster in the kitchen, and that's totally okay. Discuss with the hiring manager how you were able to recover from a disaster while baking.
"One disaster that comes to mind would be when I was asked to make a grain free/gluten free cake as a special order. I make the cake with almond meal, thinking it would work but it was much too dry. Instead, I turned the batter in small cookies and re-made the cake batter using coconut flour. I gave the cookies to the customer as an add-on for free, which they were really happy about."
