Place kumara and garlic in a large pot of salted water and bring to the boil. Cook kumara for 15 minutes or until soft when a fork is inserted. Drain and set aside to cool slightly.

Remove the garlic cloves from their skins and add back into the cooked kumara along with the butter and milk. Mash the kumara until fluffy and all lumps have been removed. Mix in the flour, herbs, pepper and salt. Then add the flaked Regal King smoked salmon and fold through.

Divide the mixture into 6 - 8 balls and flatten slightly. Coat in flour, then whisked egg and finally panko crumbs.

Heat oil over a medium heat, drop a few panko crumbs into the oil, if it begins to sizzle, the oil is hot enough to start frying. Fry salmon cakes in batches for 3 - 4 minutes on each side or until golden. Drain on a tray lined with paper towels.

Cakes are great served with a green salad or poached eggs.
