The kitchen staff
The kitchen staff begin their day at three o’clock in the after noon. The second chef, David, is a very good cook and he is able to make Anna’s work when she is away. David does his work with the help of his apprentice Jim. He makes pâtés, ice cream and desserts. David also prepares meat dishes for the main course and then Anna cooks them.
Jim, the apprentice, works two months already, and has learned a lot of things in a short time. Jim thinks that a chef’s job is rather difficult. He is sometimes so tired in the evening that at home he can do nothing but fall into bed. But this work is interesting for him. He cleans, cuts and prepares the vegetables and makes fruit salads. He learns to make garnishes and decorations on the dishes. He is happy because David fully trusts him. Today he will make the hors d’oeuvres, some of the entrees, main course and dessert dishes.
