As I noted in a previous post, I found choice boneless chuck for $2.95/lb. and BB or St. Louis ribs for $1.99/lb. What I didn't notice in the ad was that they also had all 750ml bottles of wine, when you purchase 6 or more, for 30% off, including sale items. So, back to the store and three cases of wine, six racks of ribs and thirty pounds of chuck later, it's hamburger time. I have an electric grinder with 1/8" and 1/4" plates, which one should I use and should I grind it twice for ground chuck? I have an abundance of bacon and am considering grinding a pound or so with the chuck, is this recommended? The ground meat will mostly be used for hamburgers with an occasional meat loaf and spaghetti sauce thrown in.
