Serious question. In general, what are the laws or customs regarding the treatment of the items on the Seder plate? Are they to be considered commonplace or holy? Does it differ before and following their usage at the Seder? Should one differentiate between the items which we bless and consume, and those we don't?
I just read here: https://halachablog.com/2016/04/13/the-shankbone-and-the-egg-at-the-seder/ that we actually eat it, since it was forbidden to leave it uneaten after a day.
