Peel the potatoes, cut into half and slice thinly. Put the slices into a heatproof container, cover with plastic wrap and microwave for 5 to 6 minutes until tender.
Transfer the potatoes to a bowl, and mash up roughly with a spatula or something while still hot.
Heat the butter in a frying pan and stir fry the ground meat, finely chopped onion and carrot. When the meat changes color turn off the heat. See Hints.
Add the stir-fried ingredients to the potatoes, and mix everything together until well combined and moist.
Divide the mixture into 6 to 8 portions, and form into oval patties.
Coat the patties in flour, beaten egg and panko in that order. Use your left hand for the flour and egg, and your right hand for the panko to prevent your hands from getting too messy.
Deep fry the patties in oil preheated to 180°C.
Turn them over to fry until golden brown on all sides.
Drain off the oil very well, and they're done.
When cut open, they look like this.
Serve with your favorite sauce.
Story Behind this Recipe
My grandma used to make these delicious croquettes with meat and vegetables in them. I remembered them suddenly and really wanted to eat them again, so I recreated them the best I could from memory. These multi-ingredient croquettes are really delicious (although they'll never be able to beat my grandma's).
Mash the potatoes roughly to retain their floury texture. In Step 3, some moisture will come out of the vegetables, so once they are sautéed, tilt the pan and suck it up with paper towels. If the vegetables are still watery the croquettes may fall apart while deep frying.
