Spaghetti in Kale Sauce

1. Bring a salted pot of water to a boil.
2. In a small pan, sauté 2 cloves of sliced garlic in 2 tbsp olive oil on medium heat for a few minutes. Set aside.
3. When water is boiling, add 1 bunch of de-stemmed kale leaves and cook until tender (about 5 minutes).
4. Using tongs, add kale to a blender along with the garlic and oil, a splash of hot water, 1/4 cup pine nuts, juice of 1 lemon, and a pinch of salt.
5. Blend until a thick purée forms, then add more salt and pepper to taste.
6. Cook the pasta (1/2 lb spaghetti) in the same boiling water the kale was in.
7. Reserve 1 cup pasta water before draining the pasta.
8. Return pasta to the pot and add the kale sauce, adding a splash of pasta water if needed.
