Combine mashed potato and pork giniling in a bowl. Mix well.
Add one egg and all-purpose flour. Mix well.
Beat 2 eggs in a bowl. Arrange the panko breadcrumb in a separate bowl. Scoop around 2 tablespoons of mashed potato and pork giniling mixture and then form a ball-shaped figure using your hand. Dip in beaten egg then dredge or roll on the Panko breadcrumb. Make sure that the ball mixture is coated properly.
Heat the cooking oil in a cooking pot. Once the oil gets hot, fry the pork giniling croquettes in medium heat until the color turns golden brown. Turn the croquettes over to cook the opposite side.
Remove from the cooking pot and arrange in a plate lined with paper towel. This will absorb the oil.
Remove the paper towel from the plate leaving the perfectly cooked pork giniling croquettes in the plate.
Serve. Share and enjoy!
