Cut ham into 5mm cubes. Defrost edamame and remove beans from pods.

Peel satoimo and cut into bite-sized pieces. Sprinkle with a little salt and rub to remove sliminess. Wash thoroughly and drain. Place in a microwave-safe container, cover loosely with plastic wrap, and microwave at 600W for 5 minutes until tender.

Mash satoimo roughly in a bowl. Let cool slightly, then mix in ham, edamame, salt, and pepper.

Divide into 6 portions and shape into oval croquettes. Coat each in flour, beaten egg, and breadcrumbs in sequence.

Heat salad oil in a pot to 170°C. Fry croquettes until golden brown on both sides.
