Even though it's easy to find ready-to-drink chai in grocery stores, chef and author Maneet Chauhan recommends brewing it from scratch using fresh spices, "because the result is much more flavorful and robust," she writes in the newly released book Chaat, co-authored with Jody Eddy. "Either black or green tea can be used depending upon your strength preference, but traditional Indian chai is made with black tea from Assam. Black tea results in bolder-tasting notes, while green tea leads to a milder flavor."
