Start by peeling and shredding about four medium starchy potatoes. Rinse under cold water to remove excess starch, then pat dry thoroughly.

In a large mixing bowl, combine the dried shredded potatoes with shredded mozzarella, flour, and salt. Stir gently until well mixed.

With clean hands, portion the mixture and shape into uniform sticks, about 4 inches long and 1 inch wide.

In a heavy skillet, pour enough oil to cover the bottom, about 1/2 inch deep, and heat over medium-high until shimmering.

Carefully add a few sticks to the hot oil and fry for about 4-5 minutes on each side until golden brown.

Once golden, use a slotted spoon to remove sticks, letting excess oil drip off. Transfer to a paper towel-lined plate.

Serve the sticks warm with marinara sauce or garlic aioli for dipping.
