Fill up a big 5-quart pot with water and toss in a tablespoon of salt. Add the peeled and quartered potatoes, then boil until soft enough to poke easily with a fork. Drain all the water out, mash the potatoes with butter, and let it cool completely. You can make this step a day or two ahead if it helps.

In a big bowl, toss together the cooled mashed potatoes, shredded mozzarella, chives, egg, and flour. Mash everything until it's all one mix. If it's too sticky or wet to hold its shape, sprinkle in a bit of flour at a time and mix again.

Scoop up a big spoonful of the mix and squish it into a 1/3-inch-thick round patty with your hands. Press both sides into bread crumbs until completely covered and set them aside on a board. Keep at it until all the mix is used up.

Get a large no-stick skillet heated up on medium with just enough oil to coat the surface. When the oil's hot, set the patties in a single layer (don’t squish too many in at once). Let them go for about 3-4 minutes each side until crispy and brown. Use two pans if you wanna speed it up.

Move the finished pancakes to a plate lined with paper towels to soak up any extra oil. Dish them up while still warm and add a dollop of sour cream on top or serve on the side for dipping.
