Most years I grow a row of a melon from Afghanistan called a kharbouza. It's a big melon, ten or 12 pounds, and problematic to grow. The flesh is green, crisp, refreshing, not overly sweet. I bring a few to market but keep them in my truck. People have to ask for them. Over time, immigrants from Afghanistan, Iran, Uzbekistan, and even far-western China have learned that I have these rare melons, hidden.
