Allow mixture to cool in the fridge before rolling into balls.
Roll potato mixture into balls using a heaped teaspoon for each. Generously roll in seasoned flour, then dip into egg and lastly a good coating of breadcrumbs.
Allow to chill in the fridge for 30 minutes before frying.
Heat oil for deep frying and fry the croquettes for +- 4 minutes or until evenly golden and crispy and cooked through in the centre.
