Made this today and it's very good! Used 2/3 cup xtra virg olive oil, 3 tbsp pine nuts, and grated some asiago instead of parmesan. It's oil predominant, however, so amount could be modified yet. Didn't use an ice bath but ran under cold water, nor did I do any chopping but placed leaves into blender as they were. The blender knew what it had to do! 5 stars for flavour, ease of prep, clarity of recipe,(even though I didn't follow meticulously!) Thanks, sugarpea!
