I can clearly remember the first time I ate purslane. I was eight, and the ayi who worked for my family had brought back a bag of purslane from her home province in southern China. She made them into golden crisp purslane bing (饼), or pancakes, and I was instantly smitten: It was somehow decadent, as pancakes were a rare treat, but also very healthful from the succulent crunch of the purslane.
