Basic burger rub of any type for me with just a splash of Thomas sauce (Ive only found it at Fresh Market but its a very mild marinade which seems to have a heavy olive oil texture to it) with deer burger--mix all that in a big mixing boil and then my kicker is I chop up a Jalapeno and throw it in there as well and patty out prior to throwing on grill. The jalapeno cooks down to provide just a small amount of heat while almost giving it a sweet flavor. Best deer burgers I've ever made
