My burn time on the walnuts turned out to be around an hour a gallon before pulling it indoors to finish at 219 degrees. Maybe someone else knows better about pecan but I imagine it's around the same. It is fun if you have the time on the weekend and don't mind keeping an eye on the pan, i went with one of those rectangular pans they use in catering for maximum surface heat, (maybe 10 bucks and "stainless steel - right). It is possible someone with think you're cooking meth in the backyard though, it's a lot of boiling!
