We call them potato patties and this is I my favorite food of all time. My mom took leftover mashed potAtoes and added an egg, a few spoons flour to bind it, finely minced onion,pepper and salt. Then she fried them in a skillet with oil. As soon as they were really dark crunchy golden brown on one side she flipped them. When the second side had a dark crunchy crust ,she put them on paper towels to drain and salted them liberally. Getting the crust and salting the outside is crucial !!! Oh my , I can eat them hot,cold,or anywhere in between.We had them with other things as a side...pinto beans,fried or bbq chicken, ribs,etc. I never think they are bland. If I ate only the patties as a meal,I dipped them in ketchup.I still make them but I just buy the mashed potatoes at costco and serve the first tub as bought and make potato patties with the second tub. I do t like peeling potatoes,and Costco ones are good.
