I was tinkering with my Caldera Keg F and successfully steam baked a muffin. For anybody that might be interested, here's what I've done so far. All tests were performed in my kitchen, since it's too hot outside to cook anything — unless it involves charred mammal flesh over charcoal. The fuel used was Crown NEXT denatured (95+% Ethanol).
Temperature control. I wrapped the standard 12-10 stove with foil to cover all but one air intake. It allowed the standard stove setup to burn for 29:15 on 30ml and maintained a boil of about 1" of water in the bottom of the keg from about 5 minutes through the end.
The 'oven'. I cut a soda can down to 4" high as a base for the muffin pan which was an old, small cat food can. It works out that normal mid-sized paper muffin cups fit these fine.
The software. Cheap packaged muffin mix per package directions.
Anyway, it took just over 20 minutes to bake a muffin to completely done. I did this with 25ml of fuel and will try a lower quantity in the future since I had a couple of minutes of burn after I started eating. The only down side was that the reduced air intake caused quite a bit of soot build up on the bottom of the keg.
My next step is to fabricate a stand to stack a couple muffin tins – something a little easier to carry than a cut up soda can.
Have fun,
Jim
