@Benjamminn I have never used turkey skin in a brat so I am not sure how that will go, I have a feeling even grinding it through a 1/8 plate is going to leave you with some shredds of it, but like I said, I have never done it so I can’t say for sure. As far as fat content with 55% Lean and 45% having about 30% fat content you will be on the lighter side of what I would recommend but if you use carrot fiber and cold phosphate you should be all good!
