King Arthur Flour catalog sells Portuguese muffins mix. I've never heard of these flat bread before. They are similar to English muffins but a bit sweeter and don't have "nooks and crannies". The Portuguese call them Bolo Lêvedo. They are cooked just like English muffins, in a griddle or cast iron skillet on a stove top, not in the oven. KAF recipe bakes them in the oven.
