Tonight and tomorrow only, Beacon Hill Bistro will be serving piballes. Piballes are baby glass eels, and they’re only available for three weeks out of the year, so this is a rare opportunity indeed. Expect a fairly classical preparation, with small portions of the piballes served with olive oil, ramps, and chili. Though the tiny delicacies sell for $140 a pound, BHB chef Jason Bond told us that he “won’t charge Le Bernardin prices” and, in fact, that the restaurant probably won’t make any money off them. He does, however, expect them to sell, noting that despite the recession, this year, the restaurant sold more white truffles than ever before. Bond only ordered half a pound of piballes, so those eager to try them might want to make a reservation tonight.
