I'm interviewing for a Pastry Chef position and will be asked to prepare something onsite to showcase my skills. This will be the first time that I've been asked to do this. I'm assuming that I'll have a limited amount of time. My skills are strong as I'm currently working as a Pastry Chef. This would be a new venture. What would be the quickest thing to prepare that still shows some technical skill? I might mention that this kitchen presently does nothing from scratch which is why they are hiring a chef.
