What type of establishment will you be cooking in? a restaurant ? do they serve dessert. If I was you I would get hold of a menu and see whatyou can cook offf it and practice what you cant

DH is a Head Chef ( qualified for ten years plus) and really they want to see how you can handle the pressure of the kitchen at a certain time of day and what you can cook for them off their menu....

Plenty of Chefs start out a cooks so just because you arent qualified persay dont stress, Any woman / mother can cook in a kitchen after doing it at home for years, but its how well you handle the pressure to cook in a time frame. Customers only want a ten-15 minute wait for entrees andthen a further 15 minutes for mains etc... its about keeping it all running smoothly

PM me if you would like anymore help
