I have always used both, beef fat stays put in your grind where as pork will melt out in many cases. I always try to keep 70/30-80/20 or there about. If you like grilling, put 1lb of bacon ends per 10lbs of grind. Make all your neighbors come visit! Adds to flavor & the aroma will make a dead man set up and ask for seconds!!

The cowboy candy juice is great in wilted/sautéed greens.
