Just over a year ago, Sharmilla Lalchandani and her family -- son Ravi and daughter Laxmi -- took over a failed convenience store at the east end of the Boulder Mall, then set out to transform the place. Sure, you can still buy cigs and a carton of milk here. But now the spicy aroma of chai hangs in the air, and there are glass cases holding food such as curries and savory Indian pastries, to be eaten on site or taken away. The store also carries a selection of ingredients and packaged items from around the world, including marmalade and digestive biscuits from England, olive oils from Italy and Greece, tamarind pulp, fish sauce and Indian spices. Fortunately, more often than not, a member of the Lalchandani family is around to help you figure out how to use them.
