Pre-heat oven to 150 degrees centigrade.
Pick nettles on their stalks (try to get them young when the stalks are still delicate but the leaves are not too tiny)
Wash the nettles and pat dry
Lay on a baking tray (don’t pile them up too much) and douse fairly liberally with good quality sesame oil, use a pastry brush or similar to make sure all the leaves get a bit of oil on them
Sprinkle with sea salt
Bake in the oven for approx 10-20 minutes, check regularly, depending on the size, the time changes a lot. When they have gone darker green and crispy they are done (if they go brown, they are burnt).
In the meantime mix a teaspoonful of miso paste with 2 tbsp mayo (vegan mayo works fine here) and serve on the side for dipping
