This will be short and simple post. I use a turkey fryer to do my boils outside. We have noticed that you get a lot of heat loss to the sides of the burner and one of our homebrew club members (Brian Lesperance) came up with an idea on how to get just a little bit extra from your propane burner. I have finally gotten around to making the brewing ring that he made and I can say I have gone from a decent boil, to a vigorous boil. Not only is the boil more intense, but it comes a lot faster as well. All you need is either some aluminum flashing or in my case, 2 pieces of 18″ X 24″ sheet metal. The sheet metal I got was in the heating duct section of my local Lowes and one edge had folded over grooves which I used to place the other end into. I folded the straight edge over onto itself and inserted it into the grooves on the prefabricated side and hammered them in together. Below is the result of my half hours worth of labor. You do have to cut a slot into the ring for your propane hose.
