The do not open early spoiler spaces were so funny. Thank you for doing this. I've considered doing this as well, but never got around to actually starting an advent calendar. So glad you're doing this.
And not on to story #1: I can totally see Clark doing this for their first non-catastrophic Christmas as a married couple. Had to look up the Weihnachtsgurke, though. Really not s tradition I have heard of around her. But it's so funny that even Clark has to use German recipes for some decent Christmas cookies.
Vanillekipferl are a great idea. Maybe I have to try my hand on some of these as well. Or Lebkuchen. Mmhhh!
