Brainstorm a list of your favourite dishes. Each dish should be comprised of five or more ingredients. Choose one dish from your list that everyone in your group likes. Find a list of its ingredients from a recipe or a product label.
EXAMPLE: Kung Pao Chicken is made with chicken, peanuts, onions, red peppers, Sichuan peppercorns, ginger, garlic, oil, cooking wine, salt, soy sauce, vinegar, etc.

The farmer pulls the peanut plants out of the ground and leaves them in the field to dry. The peanuts are then collected and separated from their vines. They are dried for some more time and then taken to the market for sale.
