A simple way to "bake" that I've used over the years can be done one of two ways. The first, and easiest I think, is with a product called the "Bakepacker." I don't know if it's still available but essentially it's a circular grid that fits in a pot; the grid should be the same diameter as the pot so it takes up the entire bottom of the pot. Water is poured into the pot until it reaches the top of the grid. The batter of your future baked good is mixed in a plastic bag and then spread out in the bag over the surface of the grid. Roll the top of the bag down; don't seal it. Place the pot lid on top and put the pot on a stove. Once the water has boiled you can move the heat down and let it simmer for about 25-30 minutes. After that point, take it off the heat and let it cool. When everything has cooled down you will find the contents of the bag have "baked" to perfection. Essentially you're steaming the food and not baking it but I've done this with cake mixes, bread mixes, etc. and it comes out pretty well; although breads don't look "golden" brown when they come out of the bag. For cakes I've sprinkled on some confectionary sugar or made a drizzle icing by adding water tot he confectionary sugar and laying it on the cake. Like anything else, your imagination is the only thing limiting what you can do. What I like about this method is it's essentially a "boil & bag" means of baking. There are no dirty pots because all you're doing is boiling water; the bag ends up in your garbage and there's nothing else to do.
The other way I've baked in the pan is to use what is essentially a bundt pan. Mix up your ingredients and pour them into a greased or buttered bundt pan. Place a small aluminum can in the chimney of the pan, place a lid on it and put it on your stove. Heat will come from below and also travel up the chimney of the pan and reflect off the lid down onto what is baking. Again, I've used this set up for years and, although everything you back is circular and has a hole in it, the results have always been well received. Years ago there was a company that made these ovens called the BenDonn oven. From what I understand, they two guys who came up with this had the first names of Ben & Donn; go figure. Anyway, it works and it's a nice way to give a student a birthday cake when their on a required school trip and would rather be anywhere else in the world.
That's all for now. Take care and until next time..be well.
