Good kail is half a meal

Kail or kale is a hardy vegetable that supplies many vitamins and is good for health though not all that palatable to many tastes. It was once a standard crop in Scottish gardens where it stood up to the climate well and gave its name to a homely style of writing "kailyard". This saying seems to tell us that the basics of life can usually be got but the luxuries require more effort. It also suggests not despising the ordinary, perhaps echoing the saying, "Never despise the bridge that carried you over".
