Place potatoes in a medium sized pot. Cover with water and add salt. Bring to a boil. Reduce heat and allow potatoes to cook for 15 minutes.
Add green peas and continue to cook for another 5 minutes or until both potatoes and green peas are very soft.
Heat half and half in a small saucepan. Remove and set aside.
Remove potatoes from heat and drain off water. Add half-and-half, butter, and pepper. Mashed till well combined. Allow mashed potatoes to cool slightly.
Place corn flake crumbs on a small plate. Coat a non-stick fry pan with 2 tablespoons of vegetable oil.
When potatoes are cool enough to handle, shape into patties about 2½ inches in diameter and ½ inch thick. Press patties onto corn flake crumbs on both sides.
Place on hot fry pan and fry for 3 to 4 minutes on each side. Do not over crowd pan. Fry in 2 to 3 batches.
Remove and serve immediately.
