Bring water to a boil and flash cook (<2 min) nettle in the water. Take out and drain, keeping the water coming out of the leaves to use in the recipe (it will be bright green and packed with nutrients)
Combine nettle with 1 garlic clove, 1/2 of olive oil, a pinch of salt and 1/2?of the parmesan if you are using it, and add a bit of nettle water. Whiz in the food processor until smooth.
Taste and add more garlic, olive oil, salt, or nettle water to taste, and repeat.
Take out of food processor and serve immediately with pasta, vegetables, fish or meat. If you have made a lot and won't eat it in the next day or two, it freezes really well. Enjoy!
