Weigh, measure, and mix ingredients according to recipes or personal judgment, using various kitchen utensils and equipment. Portion, arrange, and garnish food, and serve food to waiters or patrons. Observe and test foods to determine if they have been cooked sufficiently, using methods such as tasting, smelling, or piercing them with utensils. Wash, peel, cut, and seed fruits and vegetables to prepare them for consumption. Carve and trim meats such as beef, veal, ham, pork, and lamb for hot or cold service, or for sandwiches.
