Wash, dry, and mince the rosemary to make it easier to pound.
Place the garlic in the mortar with a little salt and crush until it is a fine paste.
Toss in the minced rosemary with the garlic and pound until it resembles a paste. This will take at least 3-5 minutes.
Add in the pine nuts and crush until incorporated; about a minute.
Add in the cheese and incorporate for 1-2 minutes.
Slowly drizzle in the olive oil while continuing to grind. You can do more of a stir motion now that everything has been made into a paste.
Season with salt and pepper to taste.
