In a large cast iron frying pan or Dutch oven, fry salt pork slices until golden brown. Remove and set aside. Add shrimp that have been lightly floured and cook until both sides are pink; turning often. Remove shrimp and add a little cooking oil; add potatoes and onions and cook until soft. Add enough water to make a thick gravy. Add shrimp, salt and pepper. Cook until heated through. Serve with grits.
The grits are also good with grated cheddar cheese and a can of Ro-tel tomatoes added to them. My sister likes the shrimp served over potatoes, my brother's favorite way is with rice and for me, the grits.
