One of my favorite activities when traveling is to visit local food markets. Last week, while wandering through the produce section of a wet market in Shanghai, I found something I’d never seen before. A large unmarked basket was full of miniature bright red fruits freckled with light brown dots that resembled crabapples. They had long green stems attached, and visible sepal crowns at the bottom. According to the friendly wrinkled-faced vendor I had stumbled upon haw fruit.
