In a professional kitchen, it's all about being efficient, staying organized, and keeping everything clean. A key tool that chefs use to keep this in check is the insert. Inserts, which you might also hear called food pans or gastronorm pans, are available in different sizes and materials. They’re super handy for all sorts of things like storing, preparing, and serving food. So, whether you're just starting out in the kitchen or you've been cooking for years, knowing about the various sizes of inserts and how to use them is super important for making your kitchen run smoothly.
