You will have to tell me if you disagree, but I don't think I've ever met a moist panettone.
The one Big Brother brought home for Christmas was thisclosetonotdry. (As
with all baked goods, the panettone is best eaten the day it is baked.) In previous years, I've sliced, toasted and buttered for a few days and then dumped the rest. In the spirit of wasting
not, I found the best solution to use up the leftovers.
