Pick your nettles - I suggest wearing gloves - Take just the top four leaves off each plant. Try to pick nettles that are taller than the back leg off a dog, especially if your at the side of paths. And ensure you pick the nettles before they come to flower. Rinsing them is advised.
Scrub the potato and chop it up finely.
Chop the onion up finely.
Chop the nettles finely. I hold them with a spatula to do this - it stops you getting stung.
Melt a good sized block of butter in the pan
Sweat the onions off in the pan
Add the potoates and gently fry them off
Add the stock, till it’s just covering the potatoes
Simmer covered for 15 minutes
Add the nettles and stir in fully - They loose their sting as they are heated.
Mash the mix - either by beating it with a spatula or with a masher. I added more stock to do this.
Plate up and enjoy.
