I have tried making turkey burgers with a recipe I like, but no matter how I try to cook them, direct heat, indirect heat or in the oven, they turn black on the outside by the time they are done on the inside. The original recipe said to cook them using the broiler. There is no added sugar in the recipe so I am at a loss as to what is causing this. My latest thought is that maybe the egg white, used as a binder, is the culprit. They taste great exceot for the burnt parts. Any Ideas? Thanks in advance for any thoughts or ideas.
