Karengo: A Special Seaweed

Karengo has been an important food source for a long time. It is known for its unique taste and how it can be used in different meals.

A Traditional Food

Māori people have traditionally collected karengo from the shores. They have used it in their cooking for many years. During World War II, Māori soldiers were even given karengo to chew while marching. It was a good source of energy and nutrients.

This seaweed is found in many places around the Southern Hemisphere. It grows along the coasts of South America, including Argentina, Chile, and Peru. You can also find it around Australia and New Zealand, including Macquarie Island. The first place it was officially identified was the Auckland Islands. In Chile, this seaweed is known as luche.

What Karengo Looks Like

Karengo can look different depending on where it grows. Its fronds, which are like leaves, can vary in shape and color.

Shape and Size

The fronds of karengo can grow up to 10 centimeters (about 4 inches) long. They are usually flat and can have wavy or lobed edges.

Colors of Karengo

The color of karengo can change a lot. It might be light brown or yellow. Sometimes, it can have light red edges or look a bit faded. When the seaweed releases its reproductive parts, the edges might turn a whitish color.

How Karengo is Used in Food

Karengo is a versatile ingredient in cooking, especially in areas where it grows naturally.

Collecting and Preparing
