Cut pork roast into 2" cubes, sprinkle with salt and pepper and mix together (I use my hands so it's evenly distributed). Set aside.
3-4 lb Pork shoulder or Boston butt, 2 tsp Salt, ½ tsp Black pepper
In braising pan (or large heavy bottomed sauté pan with lid) over medium heat, cook diced bacon until crispy. Remove with a slotted spoon and set aside.
4 Bacon strips, diced
Turn up the heat to medium-high. Add pork cubes to pan and allow them to brown, only turning a few times to ensure all sides are browned.
3-4 lb Pork shoulder or Boston butt
Using tongs, remove pork and set on a plate or in a bowl.
Turn heat back down to medium. Add onion to pan and cook a few minutes to soften. Stir in salt and garlic, cook another minute.
1 Onion, diced, 1 tsp Salt, 3 Garlic cloves, minced
Add chicken stock, stir well. Slowly whisk in sour cream and milk. Whisk together until everything is blended well. Stir in sage leaves.
2 cups Chicken stock, ¼ cup Sour cream, ¼ cup Milk, 3 tbsp Fresh sage leaves, chopped
Add bacon and pork back to pan and reduce heat to low. Cover and let simmer 1 hour.
After 1 hour, turn the heat up to medium-high and allow the sauce to reduce to a thick gravy, about 15-20 minutes. Stir often to prevent sticking.
Serve over home-ground grits or polenta, rice, noodles, or mashed potatoes. This is the true definition of a nutritious comfort food.
