With summer fast waning and the autumn fruits making their way to market, it's time to turn to one of my favorite holidays. The Mid-Autumn Festival or, as many of us call it, the Harvest Moon Festival, celebrates the brightest and fullest moon of the year. It was once a time for families to relax and enjoy finally the fruits of their summer labor. Nowadays, in that peculiar way modernization and urbanization has of thinning out traditions, people might simply exchange moon cakes or go out to eat at their favorite Chinese restaurant. A few purists will try to hike up a hill for a midnight picnic with hot tea. Or, if you're Andrea Nguyen, you spend days making your own moon cakes from scratch.
