and fanatics put in the whole door
Yeah, our minhag was to scrape off some woof from the front and back doors of the house but my parents eventually discontinued that minhag and switched to just the key for three reasons:
1)People kept getting splinters on their tongues.
2)They were afraid of the expense of buying new doors every 10 years
3)The back door was switched to a metal one during some remodeling and it’s harder to back metal chips into the challah.
It’s good for me that they switched as well, since now in E”Y I also only have a metal door.
On a less serious note:
When do you eat the challah, at the night seudah or the morning one?
Do you make one challah, two or even three?
