Step 1

Heat a pot of salted water for cooking the pasta. Cook according to package directions, then drain in a colander.

Step 2

Heat a small saute pan over medium-low heat. Add oil or water/broth, and saute the garlic for 2 to 3 minutes, stirring frequently. Reduce heat if necessary so that it doesn't brown. Transfer the garlic to a blender.

Step 3

Zest one of the lemons, and add the zest to the blender along with the water, cashews, arrowroot, and salt. Blend until completely smooth.

Step 4

Cut and squeeze the lemon(s) to get ⅓ cup fresh lemon juice. Set aside.

Step 5

Pour the blended sauce into the pasta pot. Whisking, cook over medium heat until thickened, about 5 minutes. Remove from heat, and whisk in the lemon juice. Add the pasta, and stir to combine.

Step 6

Taste for seasoning. Serve with fresh parsley or basil, vegan Parm, and black pepper, if desired.
