Slice the potatoes into bite-sized chunks. Keep the skin on.
Add 300 ml of vegetable oil into a frying pan
Add the potatoes and fry for about 7 minutes on low heat. (Insert a toothpick into the potato. If it is easily inserted, the potatoes are finished)
Occasionally stir and rotate the potatoes
Remove the potatoes from the oil. (Fry a second batch of potatoes using the same method if all the potatoes won't fit into your frying pan)
Add the sugar, mirin, honey, and soy sauce into a large pot
Heat until boiling. Occasionally stir while heating so bottom doesn't burn
Add the fried potatoes into the pot and mix with the sauce
Add some sesame seeds to the pot and continue mixing
Once fully mixed, turn off the stove, remove potatoes from the heat, serve, and enjoy!
