Saw a woman in front of 152 Mott yesterday selling some interesting tamale-like things to locals. As soon as she saw I was interested in buying one, she murmured "no-no-no-no-no" and went in a corner until she thought I was gone. I looked back to see she was selling them again. Anyone know what these were? Did I break an unwritten chowhound code? Has this happened to anyone else re street food?
