This weekend I am taking the scouts on their monthly excursion. We plan to drag sleds up a canyon. Hopefully there is snow. Anyways, for breakfast, I am making omelets and want to also try my hand at baking in a bag. The omelets are done by putting an egg with stuff in a freezer bag, then submerging the bag in boiling water until cooked. I would like to do the same with muffins. I have never baked muffins like this before and was wondering if anyone had any advice. I know sarbar mentions baking on her website, but I couldn't find anything about this method. Is that because it doesn't work? Also, sarbar and others have mentioned steam baking in other posts. What exactly is that? Thanks.
