Begin by roughly chopping your basil, peeling your garlic, and chopping your garlic scapes.
Juice and zest your lemon. If you'd like to toast the pine nuts, do so now.
Add all of the ingredients to a food processor and blend until mostly smooth.
If you like a smoother, runnier pesto, add a bit more olive oil. If you like it a bit more chunky, leave it be.
You may need to scrape down the sides and blend multiple times.
Taste and add more salt if needed.
Add the finished pesto to a bowl and garnish with an extra drizzle of olive oil (optional).
