To make this basil pesto, crush Garlic (1 clove) and Pine Nuts (2 1/2 teaspoon) using a mortar and pestle. This is key to a delicious pesto sauce.
Add Fresh Basil (1 handful) and a sprinkle of Sea Salt (to taste) and crush once again, pressing hard until you get a creamy consistency and the leaves have almost disappeared.
Add the Parmesan Cheese (2) and Pecorino Romano Cheese (1 tablespoon) and continue to mix through, to make a flavoursome pesto.
Pour a generous drizzle of Extra-Virgin Olive Oil (to taste) in the pesto and crush through, adding a little bit at a time to the pesto, as you go. Once done, you can serve it with your favorite pasta.
