True confession: I joined Twitter to follow a curry truck while I was living in the San Francisco Bay Area. The Bay Area had plenty of Indian buffets, but Indian street food was hard to find.
Back here in Kolkata, India, there's street food everywhere. Puffed rice tossed with pungent mustard oil, onions and chilies. Indian wraps with a layer of egg, crispy phuchka shells dunked in tangy, tamarind water.
What I didn't expect to find: a food truck.
