Also, no matter what, DO NOT watch/show The Life of Brian on Holy Friday, since that would be the ultimate sacrilege! Which is something I would of course never dare to make a yearly ritual out of.
My mother had this weird obsession that you couldn't eat meat on Good Friday, even though she never cared about religion at all. Guess what I'm having tomorrow?
To circumvent the rule of no meat on Good Friday, in Germany the "Maultasche" (mouth bag) was invented, also called "Herrgottsbescheißerle" in Swabian dialect (little God cheaters). The meat is minced and colored with spinach and then pasta dough is put around it, so "God and your neighbors can't see the meat inside".
