great deer burger
Here's something to try. Locate some beef suet in your local supermarket. This the big hard chunk suet. Freeze it. After coarse grinding your deer meat use a cheese grater and grate the suet into the burger. I use about 1 lb of suet to 10 lb of meat. Then re-grind using the finer grinder plate. I did some for a buddy in Michigan last month and now the whole town is doing it. Give it a try and let me know how you liked it.
