Just ordered my first meat grinder. A Waring MG105, I've had good luck with Waring & Presto. http://www.waringpro.com/catalog.php?pcID=139_153&product_id=534 Thoughts on ratios? Part pork shoulder(with some fat) Part pork loin Part(like 50%_ish) turkey breast(with lite, dark and skin) Part chicken And what casings should a use? Looked on LEM site, the gelatin casing looks spendy? And how safe are hog casings, I have IBS, just asking... K'
