L3F, "Slice of the Wild" recommends sour cream for fat to help game burgers stick together.

Have you ever tried mayonnaise in place of sour cream? If so how'd you like it? I am grilling elk burgers tonight, and I used olive oil because I was out of sour cream, but I didn't think of the mayo until later.

Thanks for the great cookbook! For those that don't have any idea what I'm asking about I recommend Eileen's book, "Slice of the Wild". I'm pretty sure you can still get one at John's website, but I didn't check. It's a great cookbook if you eat game meat, and if you hunt I don't know why you wouldn't eat game meat.
