Kumara is an iconic New Zealand vegetable and a staple of traditional Maori cooking. It's also known as sweet potato in the northern hemisphere and comes in a variety of colours and flavours. It's rich in anti-oxidants and one of the top potassium rich foods. Kumara is also high in vitamin A and C and full of fibre. You could really use any colour, the orange ones are just much sweeter than the red, white fleshed kumara.
