Grown from heirloom seeds, sour Mexican cukes are so small, it takes three or four to make a good bite.
Mexican sour gherkins are the size of a baby’s thumb, and have a crisp, tart flavor that tastes like a cross between a lemon and a watermelon. In fact, watermelons and cucumbers are in the same botanic family, and this species represents the missing link, figuratively speaking. Get them from Windfall Farms, Montgomery, New York. At the Union Square Greenmarket Wednesdays and Saturdays.
