I splurged yesterday and bought the grinder attachment for my KA stand mixer. The manual is pretty basic so I'd like to get some pointers before I start grinding away. I am primarily going to use it for grinding meat and prefer using leaner cuts of meat. I generally use ground pork for stir fries like braised eggplant w/garlic. Turkey for meatballs,sloppy joes and tacos. Fattier ground beef for bolognese and lastly I love Susan Goin's amazing pork burgers for the occasional indulgence. I really don't know where to start, which combinations of meats work well or what cuts of meat to look for. I eventually want to make sausages too. TIA for your help.
