Prepping the hog middles for up coming 'Nduja.
Warning: If you have never processed any type of animal domestic or game, this may not be for you. You will need to clean the middles outside, invert them and scrape all the membrane from them. In other words scrape the $h#@ out of them. If your from the South you may know hog middles as chitterlings.
Here i am rinsing all the packing salt from the middles, outer and inner. You will then need to use a bristle brush (like for dishes) and gently brush the outer membrane, Then invert the middle and do the same. YES IT WILL SMELL just like what your thinking. In the pics you will notice the color change of the middles. You will see all the membrane removed.
(Take the membrane out and bury it) HA
After you have removed as much as you can without damaging the middles, rinse, re invert, rinse again, invert and add 1/4 cup vinegar to the middles. Let stand in the vinegar swoosh em around some. Re invert and place in glass or plastic container. Add water to cover and again 1/4 cup vinegar, cover and place in fridge for 24-48 hours. After this time rinse inside and out with cold water before stuffing.
You may need to tie (truss) the stuffed casings.
Note the color change after membrane removal.
