Bread. I can make some pretty good bread, but I don't normally. Having been forced to eat bread that made me very ill all the time I was growing up has left me not liking bread.
However, bread advice: bread is easiest to make if you make it as a quick bread. It will be a batter rather than a dough. Mix your flour, your liquid, and some yeast and let it set out to develop yeast flavor. Then the rest of the ingredients go in. You will need baking powder as a leavening agent. I find that rolls are much easier to make. It's tricky to get the interior of a loaf done without burning the outside. But hey, you can make a pretty good sandwich with a roll.
Bob's Red Mill has a lot of GF bread recipes on their web site. I haven't tried any of them yet, since I don't like bread.
Bob's Red Mill also sells a GF bread mix. It makes a nice loaf if you follow the directions carefully. However, to me it tastes like rye bread, which I particularly dislike, so I've never made it again. If you happen to like the taste of rye bread, it is a very good gluten free loaf (and does not contain rye)
