Boil potatoes with skin for 20 minutes until tender, peel, cube, and mash, leaving small chunks.

Mix mashed potatoes with sour cream, green onions, bacon, salt, and pepper until well combined.

Cut cheddar into ¼-inch strips and set aside.

Flatten a spoonful of potato mix, place cheese inside, wrap, and seal to form sticks.

Coat each stick in flour, dip in beaten egg, then roll in panko mixed with cornstarch.

Fry at 350°F (175°C) for about 3 minutes until golden, then drain and season.

For a baked option, cook at 400°F (200°C) for 15 minutes until crisp and melty.
