nettles

Relatively common in Finland to use young nettles like you’d use spinach in hot dishes (soup, blanched, pancakes).

In my country soups made from stinging nettles have been eaten most likely for thousands of years.

You can buy dried and chopped stinging nettles, but they are best when you pick them fresh.

You take Finnish pancake batter (unleavened, a bit thicker than French crepes) and add blanched, finely chopped spinach or nettles.

My Bosnian grandmother used to collect stinging nettles from our garden and make burek with it.

The nettles were a by product from clearing a path to the wood hut.

A bechamel base from butter, flour and broth or cream is all that's needed to make a good soup from chopped nettles.

From the comments, it looks like eating stinging nettles is quite common throughout Europe.

You still find fresh nettles for sale in markets in Bucharest every spring.

That path had to be cleared so using those nettles was good.

I had only encountered nettles on hikes in the woods, and held them in the same category as poison ivy.

Back in the day my grandfather's neighbour would, whenever he was getting sick, take off all his clothes and roll around in the nettles.

Similarly in Romania, though it is not a pie, "Mancare de Urzici" some kidn of mash, young nettles are boiled, puréed and cooked into a sort of spinach-like mash.

When I read "A Day in the Life of Ivan Denisovich" when I was about 18, there is a mention of how in the summer they would get nettles in their gruel at the prison camp.

Nettles & fresh jalapeño salad with mayo-miso dressing is one of my favorite inventions.

I can't gather wild arugula where I live, but there is plenty of Nettles.
