@shelby my wife and I make boudin, we don’t use liver or blood. I found a recipe online and modified it to out taste. We use Boston butt for the meat.
It’s a fairly easy process. Cook pork, spices etc until rhe pork falls apart. Drain and grind everything you cooked (shallots, onions etc). Mix in cooked rice, raw chopped onion and chopped green onion). If you’re going to stuff use hog casings. You want the boudin moist but not dripping wet. I can share my recipe with you if you like, when I get time to get on my computer at home.
