Thanks so much for the assistance. I am sure I followed the recipe exactly. I used high end heritage Berkshire pork and back fat and Piedmontese chuck. I agree, the photo and the product look like much more than 20%. I checked the total weight at the end to ensure I had the right total at almost exactly 5kg. The grind looked great. Same as I use for fresh sausages and the texture is always how I like it. I have never run back fat through it however. I do recall that it might have looked more like lard than a grind and it was a frozen too. I used the 3/8 plate for the fat and pork and the 1/8 plate for the chuck. The beef chuck was not overly fat either. It does taste really good so it wont go to waste! Again, thanks guys. Really glad I found this forum and I appreciate the help and advice.
