Preheat oven to 180c/350f.
If your potatoes have dirt on the outside (mine did) wash and scrub them well, then dry with paper towel.
4 large potatoes
Pierce each potato quite a few times with a fork, then wrap each one in a piece of aluminium foil. Place potatoes on a baking tray and bake for an hour or until tender. You can test to see if the potatoes are cooked by piercing the potato through the foil with a toothpick.
Meanwhile, combine butter and garlic then set aside.
80 g softened butter, 1 garlic clove
In a small fry pan, fry chopped bacon until cooked then also set aside.
2 bacon rashers
Open the foil and allow potatoes to cool slightly (see my notes), then make a slice through the centre of each potato, about half way through. Insert a fork into the slit and fluff up the soft potato flesh inside - doing your best to keep the skin intact.
Place 1 tablespoon of garlic butter and a small amount of mozzarella cheese plus salt and pepper (to taste) into the slit of each potato and mix them together with the fluffy potato flesh.
100 g shredded mozzarella, salt and pepper
Then add remaining cheese and mix until the centre of the potato is creamy and smooth. Then top away!
250 g sour cream, 2 shallots (green onions), 1 avocado
