Plantain* coins and chips are best when cut with a mandoline slicer; the thinner the better, as they will toast evenly and yield a completely crisp product. One plantain goes a long way if you cut them like that. These chips and coins can be used to decorate many dishes. In Colombia, we buy the chips in white paper bags on the streets. When I was a little girl, we used to buy them at the entrance to movie theaters and schools. We still get them there, and the ones sold on the streets are the best, because they are always thin and crispy.
