When I pick up my freshly made (but yet uncooked) kielbasa it kind of feels a little "light" in weight. The only thing I can think of is that my grinder is injecting too much air into the meat being that the throat is so small. It only "sucks in" one chunk of meat at a time which surrounds it with lots of air. I'm using a crappy Silvercrest meat grinder that I got for $40 but it's quite small. I'm convinced that's the problem. I have at a minimum 25% fat in the sausage. Needless to say I have a new Chard #12 grinder on the way that I hope will improve the texture and weight of the final product. What does anyone think? Has anyone else had "weight" problems with their links?
