I had seen similar racks in use on a trip to the southwest and was going to purchase one in a shop. My host commented that She had gotten hers from Amazon for half the cost and I would not have the inconvenience of packing the rack for the trip home.
She was right - This rack is well made of stainless steel, durable, and has the added advantage of coming with a tool to core the seeds from the peppers. I made some jalapeno poppers, and some hot hungarian peppers on the grill last night and this rack worked as advertised. This rack would probably also work with banana peppers or any similar shaped pepper. Holds the peppers upright and allows the heat to roast the pepper evenly in about a half hour on a Weber with the lid closed (Grill was already hot from other grilling). I barbecued pork steaks and when I put them in the roasting pan of sauce to tenderize, I started the peppers. By the time I had them cleaned, stuffed, and cooked - the meat was also ready to serve. The rack also functions as a work stand while stuffing the peppers!
