I have a food dehydrator and was wonder if I could effectively dehydrate venison/beef burger? We've done jerky before but I was wondering about burger. Cook it first? Season it? How long will it keep? Our jerky didn't keep as long as I thought it would. Once dehydrated soaking it in water then using it would be the plan? Reason I'm asking is I have a couple of deer in the freezer, mostly burger and my wife wants more room in the freezer for "normal" (her words not mine...LOL) foods.
