Initial Prep: Cleanse the pig stomachs with cold water until spotless.
Preheat Oven: Get your oven heating up to 350°F (177°C).
Chop & Dice: Prepare your veggies and smoked sausage by chopping and dicing them.
Mingle the Flavors: Mix together the pork and Italian sausages, cubed potatoes, onions, and celery. Add the chopped parsley. Flavor it up with salt and pepper. Introduce the sliced smoked sausages to the mix.
Stitch It Up: Secure one end of each cleaned pig stomach with toothpicks or cooking twine.
Stuff It: Now, fill these stomachs with the prepared sausage-veggie mix. Press down as you go; the stomach will expand.
Final Touches: If the pig stomachs are too long, feel free to trim the excess. Place them in a roasting pan and add a touch of water.
Baking Time: Cover the pan with foil and bake for about 2.5 to 3 hours. Keep basting every 20 minutes using water or the pan's juices.
Golden Finish: For the last 30 minutes, remove the foil and allow the hog maws to turn golden brown.
Serving: Remove, discard the toothpick or twine, and place your cooked hog maws on a plate. Either slice them into 1-inch thick portions or scoop out the delicious filling.
