True, but she already used rum, so her
Rumtopf already has the distinct rum flavor. But because she used rum with only 40% alcohol, I think she may not have enough alcohol to preserve the fruit until the 2011 holiday season. (She does have enough for the 2010 holiday season.) So all I'm suggesting now is a little fix. Its purpose is to bridge the difference between rum with, say, 55% alcohol, which I think she ought to have used, and rum with 40% alcohol, which she did use. Specifically, assuming that she used a liter of 40-percent rum in the first place, that difference would be (1 liter * (55-45) / 100), or 150 milliliters, of pure ethanol. (Where for practical purposes, "pure" means 97% ethanol, 3% water, 0% contaminants to spoil the taste.)
