Kroket Kentang is Indonesian snack passed down from the Dutch during Dutch colonization. The original potato croquette from the Dutch has evolved to adapt Indonesian traditional snack favored by so many people.
Cut potatoes into pieces to steam for 15 minutes. To decrease the water content from the potatoes, deep-fry the steamed potatoes. This is up to you. I myself prefer steaming the potatoes.

Assemble
Take around 50 gr of mashed potatoes, press them flat with your hand. Put one tablespoon of fillings in the middle. Wrap with the mashed potatoes and seal tightly.
To make the skin crispy, dip it in egg white and roll the shaped potatoes on a bed of breadcrumbs. Dip it again in egg white and roll on breadcrumbs one more time. This will make the coating more crispy and steady.
Chill in the refrigerator for 30 minutes to let the skin set. You can freeze the unfried krokets for up to one month.
Deep-fry the chilled kroket until golden brown. Drain the oil by putting it on paper towel.
