Start by peeling your potatoes and cutting them into chunks. Place the potato pieces in a large pot, cover with cold water, and bring to a rolling boil. Cook until they're completely fork-tender, about 15-20 minutes depending on size.
02 -
Drain the cooked potatoes thoroughly and let them cool slightly. Using a potato masher or large fork, mash them until completely smooth with no lumps remaining. You want a creamy, uniform texture for the best results.
03 -
Add the shredded mozzarella cheese and cornstarch to your mashed potatoes. Mix everything together thoroughly until you have a cohesive, stretchy mixture that holds together well.
04 -
Transfer the potato mixture into a large ziplock bag and use a rolling pin to flatten it evenly to about 1/2 inch thickness. Place the bag in your freezer for exactly 30 minutes to firm up - this makes cutting much easier.
05 -
Remove from freezer and carefully cut away the plastic bag. Using a sharp knife, cut the chilled potato mixture into finger-sized sticks, roughly 3-4 inches long and 1/2 inch wide.
06 -
Heat your vegetable oil in a heavy-bottomed pan to exactly 375°F. Carefully drop the potato sticks into the hot oil, working in small batches to avoid overcrowding. Fry for 2-3 minutes until they turn a beautiful golden brown color.

Remove the crispy sticks from oil and place on a paper towel-lined plate to drain excess oil. Serve immediately while they're still warm and gooey inside with your favorite dipping sauces!
