Working in a restaurant kitchen is no child’s play. You need to know about spices, vegetables, meats, and other types of ingredients. Besides this, you need to know about knives. There are many types of knives and you need to know what each one is for. Also, there are different types of cutting boards, and you need to know how to use them.
This is just the beginning. You need to be good at working under stress. The chef is always yelling, telling everybody what to do, but not always how to do it. You are supposed to know that. You need to learn to work fast, and do many things at the same time.
The most difficult part of all, at least for me, is learning the nutritional values of every meat and vegetable. Working in a restaurant kitchen is hard, but it’s very satisfactory when you realize that the dishes are ordered frequently. That means that the people liked your food.
