Personally I find it a bit early for good tea or salt from nettles. If there's not enough for soup try gently poaching them like asparagus or adding them chopped up to stir fry. Good food
Salt I find is better made later on when there's more ???tannin?? in the leaves. I just dry them as though for tea but powder them up very finely and add to savoury dishes.
Salt's maybe not really the right word here, it's more a kind of stock.
I'm trying to cut out salt
I've been playing around with savoury stocks rather than adding the old Na+CL- to my food.
Nettles are a goodie, supposedly ideal for those who have high BP too.
If you really need the salt with them grind the leaves up, fresh or dried with a mortar and pestle and some salt crystals. Pack in an airtight baggie and use like oxo cubes.
