Toi Tangata - Taewa for Tea with Zirsha Wharemate
 

Taewa for Tea

Our nutritionist, Zirsha Wharemate, shares her experience and knowledge around taewa, a traditional staple kai crop for Māori, and her successes in the maara this season.

I can’t think of many things that are better than freshly dug new potatoes out of your own garden, slightly roasted with a bit of extra butter on the side. What makes them even better is the pride that my sister and I felt, having grown these purple gems of cultural significance from seed tubers ourselves.

Taewa (or parareka, peruperu, rīwai in other Iwi) is one of the primary names used by some Iwi when referring to Māori potatoes. Despite common assumptions, Māori potatoes are not kūmara (Ipomoea batatas or sweet potato) but belong to a totally different plant whakapapa, Solanum tuberosum

Like the common “European” potato, the two major subspecies of taewa originated from South America – but how taewa arrived in Aotearoa is up for debate. Whatever the means of arrival, our early tīpuna were quick to recognise and develop their potential as a food crop that could be grown, stored, eaten or marketed to help support the Iwi. Thanks to the continued efforts of heritage growers and other organisations such as Tahuri Whenua (National Māori Vegetable Growers Collective) that have collected and continue to maintain tuber seed banks, taewa are still grown throughout Aotearoa today.

Ok, enough of the history lesson… do they taste good, you ask? And how do they stack up against other potatoes? 

Firstly, I will admit I may be slightly biased so I’ll leave the taste testing to you, but for those who are unfamiliar with taewa here are a few interesting facts about them. 

Taewa come in a range of colours, so can add a lot of interest to a dish

  • Skin colour range: creamy-yellow, dark purple, pink/purple, pink/orange, red, creamy-yellow mixed with pink, red or purple hues.
  • Flesh colour range: white, creamy-yellow, dark purple, mainly creamy-yellow/white with purple/pink flecks or with purple/pink coloured rings within.

Taewa have unique flavour characteristics

  • No doubt in part due to the variety of skin and flesh colours, Taewa possess differences in flavour, texture and other taste attributes. Best to try them out for yourselves but popular ways for cooking them include roasting, baking or boiling them whole in a boil-up and serving them hot.

Taewa don’t need to be peeled

  • Taewa are generally much smaller in size than the average supermarket white potato. They also have a lot of “eyes” which gives them a knobbly rather than smooth shape. Rather than trying to peel off the skin, just wash off any dirt and cook them whole or in halves. If you’re not so keen on eating the skin, removing the skin after cooking is likely to be easier.

Coloured Taewa varieties possess potential nutritional and non-nutritional health benefits (compared to white-skinned, white-fleshed varieties)

  • Analysis of four taewa varieties (Huakaroro, Karuparera, Moemoe, Tūtaekuri) compared with Nadine, (common modern variety) showed that these four taewa (especially Tūtaekuri) showed promising potential with regards to energy, resistant starch, fibre, protein, mineral content (potassium, phosphorus, magnesium, iron, zinc, copper), vitamin content (vitamins C, B1, B6, niacin and folate) and potential antioxidant capacity. 

Taewa varieties include

  • Huakaroro (yellow skin, creamy-yellow flesh)
  • Karuparera (dark purple skin but yellow around the eyes, white flesh)
  • Moemoe (mottled yellow and red/purple skin, creamy yellow flesh with pink/purple flecks) Tūtaekuri (dark purple skin, dark purple flesh)

So there you have it whānau, if you haven’t yet, I encourage you to give taewa a try. They are tasty, easy to cook, easy enough to grow (because if I can, then surely you can) and if you hold on to a supply of good seed tubers each harvest, you can keep growing them year after year. 

Not sure where to get some? 

Try the local farmers’ markets, ask your local kaumātua who may be growing them or alternatively try contacting those that sell heritage vegetable seeds (ie, Tahuri Whenua, Koanga NZ Institute, Heritage Food Crops Research Trust).
