You can make this challah dough in a bread machine on the dough cycle following the manufacturer's directions. Just don't bloom the yeast first, layering 1 full cup of water, and all the flour (start with the least amount and add more flour as the machine starts to mix, if needed, until it feels as described in the above recipe), along with the other ingredients, according to your bread machine's instructions (you know how it is, some go wet ingredients first, dry ingredients last - others dry ingredients first, wet ingredients last)
