Visit Indian/Pakistani restaurant Tarka (3207 Williams Blvd, Kenner, LA, 504.471.6141) to sample papri chaat, a north Indian snack food.  The big-enough-to-share appetizer is constructed from crispy chaat wafers, cubed potatoes, and layers of yogurt & tamarind chutney, sprinkled with chaat masala spices and garnished with cilantro.  The pale pink melange, like so many great snack foods, manages to be salty, sweet, crunchy, and rich all at the same time.
