Pesto, as you know, can be made from any greens. Why not try young wild greens? You can add sour or gout to nettle - it will be even tastier!
Preheat oven to 200°C. Wash potatoes with a brush, cut in half or quarters, place on a baking sheet. Drizzle with melted butter, season with salt and bake until tender, about 35 minutes.
For the pesto, remove the stems from the nettles and place in a glass of an immersion blender. Add finely chopped dill and garlic, salt, grind into a paste.
Gradually add the seeds and add oil until you get a not very thick pesto. Add cheese and pepper, beat again. Pour over potatoes and serve.
