I just got some for the first time, and it was in the frozen section. Do I need to freeze it again when I get home, or just keep it in the refridgerator?
Yay, Ezekial bread! If you don't plan on eating most of it within the week, I'd keep it frozen. Plus, like all breads, it'll dry out it the fridge, which isn't a big deal if you always toast it. Personally, I buy mine unfrozen and then pop it in the freezer when I get home. When I want a couple of slices, I put them directly in the toaster on the highest setting, and they come out perfectly. If you keep it frozen, you never have to worry about the loaf going bad, which it does very quickly if it's just sitting out on the counter.
Ezekiel bread is kept in the frozen section at the grocery store because it tends to get stale more quickly than regular bread. If you're going to eat it right away, you don't need to refreeze it.
