ok, i think i just needed to hear a few try-it-its-probably-fine's. i was going to make beans this week and my baby cookbook said to rub off the skins... sounded so weird to me and way time-consuming, too. maybe the skin is what makes them gaseous, donno. but will try it with skins and see how it goes!
kate, i have also been giving the skins on blueberries but peeling apples and sweet potatoes. so when do we start including the apple peels? in my house we actually prefer our applesauce with the peels in there, ove always made it that way.
