Holy Schlissel?

If it's the first Shabbos after Pesach, you know everyone's looking forward to their challah. You also know that someone, somewhere, is going to be going on about "schlissel challah" and inauthentic minhagim (ritual customs). Schlissel challah, literally key challah, refers to the key-shaped challah bread that many Jews bake on the first Shabbos after Pesach (many, place an actual key inside a normal loaf, instead). Many explanations have been suggested for this custom, including focusing awareness on the gates of Heaven that are believed to remain open during the month after Pesach, as well as a thanks and request for material sustenance (see article).
