I have lived communally using an outdoor kitchen that didn't have a regular oven (toaster oven-->check), and it would have been nice to know about this back then.
This sourdough is easy and cheap...The starter I keep going is mixed in with flour, water, salt, dried garlic, and herbs(I do half white/whole wheat) and is let rise. More flour is kneaded in and spread out to about 3/4 inch thick to let rise a little more. This is chopped into toaster sized biscuits and cooked stove-top in a pan about 5 minutes each side. As needed I cut them in half and toast to perfection (inside isn't fully cooked just on pan).
Sourdough is supposed to be good for digestion etc and I have read this is partly due to gluten breakdown. It's tasty! Once a culture is going it is hard to kill and can be kept indefinitely only requiring flour and water.
I have been without an oven for about a week and it's killing me! The safety valve went bad apparently. I do have an oven in my wood stove but it's small and hard to regulate. Plus, a few years ago my husband broke the glass door and he has promised to make me a new one, ad nauseum. I just tried to make muffins which I think worked but the batter oozed onto the floor of the oven and I didn't put and tin foil down. Mmm, burnt chocolate chips.
Perhaps this will spur me to build that brick oven I've been meaning to make (replacing the mud oven that the goats destroyed).
My project thread Agriculture collects solar energy two-dimensionally; but silviculture collects it three dimensionally.
Oh, no solar oven here sorry. I've reworded the original post to avoid confusion. Shucks best of luck with the oven...but all you need is a stove and a toaster/toaster-oven to make your own delicious bread!
