Using non-stick pans
“Don’t use non-stick pans! Basically the only thing [chefs] use a non-stick pan for in our professional kitchen is egg cookery. I know people that cook almost everything in non-stick, which is a flavour killer. Nothing beats a high-quality stainless steel or cast iron pan. If you’re worried about protein sticking, get your pan VERY hot before adding oil, and you won’t have problems with sticking, plus you’ll get a much better sear leading to greatly improved flavour.” —Chef Jim Heflin
Leaving a mess as you cook
“A professional chef would also clean as they go! They will have everything prepped out which will allow them time to do this.” —Tracy Wilk, Lead Chef and Recipe Editor (Recreational Program) at the Institute of Culinary Education.
Using a microwave
“I got rid of my microwave a few years back and haven’t looked back. If I want to re-heat food, melt butter, or boil water I use my stovetop. Most chefs I know are in alignment with doing this as well.” —Melissa Eboli, owner of a personal chef and catering company
