About Kumara

What Is It?

Kumara is a root vegetable native to South America but is now popular in many parts of the world. It is also known as sweet potato and is related to the morning glory family.

It has an elongated shape, smooth, thin skin, and a firm, starchy texture. It can be found in shades of yellow, orange, red, purple, or white.

Nutritionally speaking, kumara is high in dietary fiber and potassium. It also contains vitamins A and C, calcium, magnesium, iron, and phosphorus. These nutrients make kumara a great addition to any diet as it helps promote healthy digestion and bone health.

The Origin Story 

The debate around whether sweet potato and kumara are the same is long-standing.

The Polynesian ancestors of Māori brought kūmara (sweet potato) as a food plant when they arrived in New Zealand in the 13th century. It is believed that early Polynesians had voyaged to South America and taken kūmara from there to Polynesia.

However, it wasn’t until centuries later that kumara was introduced to European settlers in New Zealand by Maori settlers in 1769.

Pre-European Maori grew several different varieties. Compared to the varieties we eat today, those kumara varieties were very small, no bigger than a finger. This led many people to believe they were two different varieties of potatoes. 

The Debates

This belief has persisted for centuries, but recent genetic analysis has shown that sweet potato and kumara are, in fact, the same plant. The only fundamental differences between them are their appearance (kumara is usually red or purple while the sweet potato is usually light orange) and texture (kumara tends to be slightly firmer than a sweet potato).

Despite this scientific evidence, many people still argue that they should be treated as two separate plants due to their distinct cultural significance. 

What Does Kumara Taste Like? 

Kumara has a mild sweetness that can range from subtle to intense, depending on how it is cooked. It also has a creamy texture when cooked properly.

Roasting is one of the most popular ways to prepare kumara; cut it into cubes or wedges, toss it with olive oil or butter, sprinkle it with salt and pepper (or any other spices you like), then bake until golden brown and tender.

You can also boil or steam kumara for mashing or puréeing for soups or sauces. Sweet potato fries are always a hit too!

The possibilities are endless — get creative with your cooking methods to explore all the delicious flavors of this versatile root vegetable.
