"요리법을 따르면 양파하고 배추가 필요해요."
Translation:According to the recipe, you need onions and Napa cabbage.
Sorry gentlemen, you are displaying your youth and that most, if not all of us, need to be reminded from time to time that we do not know as much about everything in this small world of ours as we think we do. We can take all human collective knowledge on every known subject, shove it up a gnats rear-end and it would roll around like a BB in a gymnasium! Like a great sage once stated, "The only thing that I know is, I know nothing."
