@margo,
I used to add Hennessey cognac to my cheesecloth fruitcake wraps, sometimes more than once while the fruitcakes rested in closed tins.
I might do some this year, while making the fruit apricot sweetened dried cranberries and my own sugared citrus peel.
Or else, a panettone, which doesn't take any booze but several dough rises. But that's a batch of work for something that disappears quickly. So are the fruitcakes, when you make a dozen, but they last and last if stored right and sliced thin.
