According to Ashkenazic practice, all egg matzo may be eaten only by the young, infirm, or aged. If you are of Sephardic ancestry, consult your rabbi.Oops.
Challah is taken.
I already ate it, don't have a rabbi, and am not exactly what you'd call young, but I'm not aged and infirm either.
Maybe I should switch to the unsalted?
And can anyone explain to me what "Challah is taken" means?
