My mom was a fast order cook and when I was a teen she got me to help her run a fast food shop our family ran for a few years. She taught me how to work in a kitchen and how to cook.
Her basic rules were … if you aren’t cooking you’re cleaning, if you aren’t cleaning you’re cooking, and if you aren’t cooking or cleaning, get out of the kitchen.
If you aren’t cleaning as you go, the food prep area will get gross and unsanitary fast. This goes for cooking at home, too.
once I had a flatmate that every time he was cooking he was leaving the kitchen like a warzone and he had used every utensil available in the kitchen. He somehow thought that it was faster for him to focus only on the cooking and after it is completed, to do all the dishes, pots, utensils, glasses, oven trays, scissors, screwdrivers, hammers, drills or whatever else he may had used.
