Peel the potatoes and chop them into equal sizes.
Boil the potatoes until it is fork tender, drain properly, and then place in a bowl. This will take about 15 minutes.
Mash the potatoes until it becomes crumbly, then season with salt and pepper.
Add butter and potato starch, then mix thoroughly until the potato mixture is homogenous and can be shaped.
Take a handful of the potato mixture, shape it into a ball, flatten it, then place mozzarella cheese in the middle.
Tuck the edges in to make a ball, seal the cracks, and make sure there is no cheese leaking.
Flatten it out to make a pancake, then set aside. Repeat the process until you run out of the potato mixture.
In a pan, put oil enough for shallow frying. Heat it, when it is hot enough, place the pancakes and fry until it is golden brown. This may take 3-4 minutes per side.
Cook until all your pancakes are beautifully golden brown, serve hot, and enjoy!
