I do my rounds a little differently:
Roll out 4 strands
Put them in the shape of a tic-tac–toe board (two down, two across, but overlap like a weave). Leave a little space between the strands.
Now go around clockwise over-under once with each strand (ie, take top right and move it either over under the strand next to it – whichever looks right; then take next strand and do the same, all around.) Now reverse direction, going over-under counterclockwise.
I rarely have enough dough to go a third time around, but you could….
Flip the whole thing over and place in round pan.
BTW – i add cinnamon/sugar in 2 ways –
1- sprinkle the top with cinn/sugar after you egg it. You can egg it with the white only b/c the sugar helps brown it…BUT this way gets the underside of the challah deckel dirty (which is why I started doing it the other way,..,
2- slit each rope lengthwise, drizzle in sugar/cinnamon mix, close the slit … the kids love the “surprise”
in any case, a gut gebentshed year!
