Set the temperature of the oven to 425°F.
Wash the potatoes. After washing, pat dry the raw potatoes with a kitchen towel or paper towel. Use Russet Potatoes or any other large baking potatoes. Use it if serving these potatoes as the main course for dinner. Choose some smaller potatoes if you're serving them as an appetiser, as these are more suited to a platter. Put the potatoes on a baking tray. Give the skins a little oil coating, and then sprinkle black pepper and coarse sea salt over the top.
Continue to bake the potatoes for 45–55 minutes, or till they are cooked, at 425°F. Cut the baked potatoes lengthwise once they are cold enough to handle. Leave a thin layer of potato inside the skin. This helps give them structure and scoop out the pulp into a basin. When serving such large potatoes as an entree, prefer to trim the top quarter of the potato. It is to create more room for cheesy fillings. Cut potatoes in half while making little ones for an appetiser.
Add salt, pepper, and a little drizzle of olive oil. When preparing the filling, place the potato skins back in the oven.
Put the potato pulp, salt, pepper, old bay, sour cream, cheddar cheese, and butter in a large basin. Mix the other ingredients with the potato flesh until well combined using a potato masher.
Add grilled corn and chives, stirring with a fork. In the last step, stir in the cooked seafood. Try it out and adjust the seasoning.
Fill the potato skins to the brim with the shrimp cheese mixture. Add the final cup of strong cheddar.
Return the shrimp baked potato to the oven and bake for another 15 minutes, or till the cheese turns golden brown. Serve with spicy sauce and sour cream, then top with more diced chives.
