Preparing for making Christmas Candy with marzipan tomorrow

I have found two Christmas Candy recipes with marzipan in a small recipe collection made by Mai Knauer. I will be making Valnøddekugler (Walnut Marzipan Candy) and Tranebærkugler (Cranberry Marzipan Candy) tomorrow. However, you have to start ½ day (night over) in advance, as walnuts and raisins need to soak in rum (I will use cognac), and the cranberries need to soak in Cointreau. I keep saving the small bottles of liqueur collected from my various flights around Europe for different kitchen activity like this.
