Here's what you do. While the leftovers are being dealt with Thursday night, scoop out a cup or so of cranberry sauce and put it in a special spot in the fridge. Sunday morning, make the following coffeecake. You'll have it on hand to serve holiday-weekend visitors, or the straggling remnants of your visiting family. At last -- an almost guilt-free solution to residual cranberry sauce! The glaze is, of course, optional.
