Kale had its moment in the spotlight in the early 2010s. All of a sudden it’s everywhere: chips, salads, and slaw. Though it may seem like a recent trend, there are places where kale has been a staple food for centuries.

Kale — Part of the Scottish Diet for Centuries

In Scotland, the traditional diet is so rich with kale that the word ‘kale’ (also spelled ‘kail’) is the same as the word for ‘food.’ There is a common saying that when someone isn’t feeling well enough to eat that person is “off one’s kale.”

Maybe the Scots just love their nutrient-dense leafy greens, or maybe they eat so much kale out of necessity. It is very hearty and able to stand up to the Highland winters. It can survive snow, ice and temperatures as low as 10 degrees below zero. In fact, a heavy frost actually enhances its flavor. Why? It encourages the plant to transform starches in its leaves to sugars. It is easy to grow in cooler climates. At the same time, it is nutritious and versatile, making it the go-to vegetable of the Scottish diet. In fact, the common term for a small kitchen garden containing vegetables is referred to as the “kailyard.”

How to Cook Kale

Traditionally, kale is prepared by boiling it with a bone, such as a beef or lamb bone, for added flavor. Then, you mash it until smooth with cream and butter.

The Scottish have a play on Ireland’s Colcannon (mashed potatoes mixed with cabbage). It a nourishing side dish called Rumbledthumps. It combines mashed potatoes and turnips with cooked and finely sliced kale. Combine the ingredients in a baking dish, cover with a sprinkling of cheese, and bake in the oven until golden brown. Kale is also a standard addition to soups and stews, where it is accompanied by other vegetables and meat in a rich broth.
