Then dice and add the potatoes to the pot and generously cover the vegetables with water. Crumble in a stock cube and simmer with the lid on until the potatoes are soft.
Add the rinsed nettle tips to the pot.
Stir the nettle tip into the soup and simmer for just 2 or 3 minutes. Then add the lemon juice and blend the soup with an immersion blender.
Taste and adjust the seasoning as needed with salt and pepper.
