Mash together your potatoes and fish. Add in the seasonings then the egg and panko. Mix well. Form into small patties, approximately 2-3 inches. Cover and refrigerate for 30 minutes or all day. I like to do this in the morning so I can can breathe as dinner approaches knowing I already have it all together.
In a large skillet over medium heat, add 1/4 cup oil. Once the oil is hot (you can drop a small crumb from your patties to see if the oil sizzles, if so, then you're ready) and pan-fry the patties 2-3 minutes on each side until they reach a golden brown. You might have to do this in batches of 3-4 patties as you don’t want to overcrowd the pan. Serve hot and enjoy!
For the potatoes
Boil potatoes in a large stockpot until you can insert a fork easily into the center of a potato. Drain, toss in the butter, cheese, seasoning, sour cream, green onions and milk. Mash until everything is combined.
