I make nettles into tea. In the spring I go for a walk down the river avon and pick the lightest green leaves, the new growth, and then wash (important especially if it's a public footpath) and freeze them later that day. By the time I've walked home all the stings have degraded so I can make a cup straight away if I want. I make the tea with four or six leaves in a strainer, and add a little honey if you like. It's supposed to be good for hayfever sufferers (as is honey) which I am, but it tastes great too.
