The document provides 5 tips for cooking authentic Vietnamese food from chef Tracey Lister, who is famous for teaching Vietnamese cuisine. The tips are: 1) Vietnamese food relies on dipping sauces for seasoning rather than seasoning during cooking; 2) when buying fish sauce, it should bubble slowly rather than quickly; 3) annatto oil adds color and flavor and keeps well; 4) chicken fat can be used like butter or cream to add moisture; and 5) cooking meat and fish on the bone retains moisture and maximizes flavor.
