Several years ago, at a bistro in Cincinnati, I had whipped ginger sweet potatoes. They weren't sweet, and I haven't managed to reproduce their side dish yet, but I came up with this tonight (to go with recipe #311662 and some roasted asparagus) and went back for seconds. Amounts are estimated, as I just eyeballed everything. Next time, I'll probably use whipping cream instead of half & half, but I didn't have any tonight, and more ginger, maybe less (or no) sugar. I also confess, I used ginger in a tube for the fresh ginger.
