Put a pot with plenty of water on the fire and a pinch of salt. Wash the potatoes and picture them like this, with no peel, just a wash. Cooking time may vary depending on the type and size of potatoes, but let's calculate that it should be 20 to 30 minutes . To check this, you only need to prick the potatoes, and you should be able to prick them without force so that you notice they are cooked.
Once they are done, drain the potatoes and let them heat up. The moment you can catch them without burning your hands, peel them. Put them in a bowl, cut them into bite-sized pieces and mash them with a fork until all the potatoes are mashed like mashed potatoes.
Then it will be time to add the spices you want for your potatoes, in our case we just add some salt and freshly ground pepper. To make it softer, add softened room temperature butter and, if you see that the potatoes are quite cold, a couple of egg yolks . Stir everything well.
You place the potatoes in an airtight container or you can conveniently cover them with clear foil and leave them for 45 to 60 minutes in the refrigerator.
Meanwhile, prepare the cheese cubes. We used soft cheese such as provolone, but you can use any that melts.
Take out the potato dough, make a ball, and in the center, with the tip of your finger, make a slit where you put the cheese (one or two pieces, depending on the size of your potatoes). Cover the potato ball with your hand and you're ready to cook.
When you have them ready, we do the breading. First you sprinkle each ball with flour (shake gently if you see any excess on the surface), then whipped egg and then breadcrumbs (you can add spices or something similar, you can make breadcrumbs at home
Translated with www.DeepL.com/Translator (free version)Put a deep frying pan or saucepan filled with olive oil or vegetable oil on the fire, when it is hot (we will maintain a mild temperature so they do not burn), gently add the potato balls so as not to burn or crush them. They cook for 3 or 4 minutes , turning them so that they get a nice golden color on each side.
Then you take them on a plate lined with kitchen paper and leave them for a few minutes to soak up the fat.
Then serve quickly so you can enjoy the melted cheese in the potatoes. Remember, you can eat them with any sauce, from mayonnaise, to garlic and even barbecue.
