Put peeled and quartered potatoes into a 5-quart pot of salted water. Bring the water to a boil and let the potatoes cook until fork-tender. Empty the water completely, then mash them with 4 tablespoons of butter. Let the mashed potatoes cool down to room temp before using. You can store these for 1-3 days before starting.

Add mashed potatoes, mozzarella, an egg, flour, and chives to a big bowl. Mash everything together until smooth. If it feels too soft to shape into patties, sprinkle in extra flour a little at a time.

Scoop a generous tablespoon of the mixture and press it into a thin disc, about a third of an inch thick. Coat both sides of the patty in breadcrumbs, making sure it's evenly covered. Place each patty on a flat surface like a cutting board and repeat for the rest.

Warm a skillet on medium heat and pour in just enough oil to coat the bottom. Toss in a batch of patties, but don’t crowd them! Cook each side for 3-4 minutes until they’re golden and crispy. For quicker cooking, try using two pans at the same time!

Move the finished pancakes onto a plate lined with paper towels to get rid of extra oil. Serve hot, adding a spoonful of sour cream on top or alongside.
