Their "3 day" aging is cheating...
it should be aged much longer.
Therefore, it can be made on 1 day, and is then aged. The aging does not count on how many days it takes to make it.
If you need help with recipes, let me know.
However, to create a truly authentic Dresden Stollen, you must completely bath the finished loaf in butter. A "dunk" in a butter bath accomplishes this quite nicely. Then it is coated with the sugar coat to seal it in. I've seen plenty of "faux Stollen" recipes that don't include the butter bath, or just brush it with butter, or simply leave out the butter entirely and just sprinkle on some powereded sugar. This is not Stollen.
Let me know if you need any more help with Stollen. We love Stollen at our Haus! It wouldn't be Christmas without it!
