Start by picking or buying fresh basil leaves. This aromatic herb forms the base of the pesto and gives it that delightful green hue.

Joanna recommends using pine nuts or walnuts for a delicious nutty undertone. Combine these with grated Parmesan cheese for a creamy and savory texture.

A couple of garlic cloves are essential to give the pesto its characteristic zing. Adjust the quantity to your preference.

In a food processor, combine the basil, nuts, cheese, garlic, and a touch of salt and pepper. Slowly drizzle in the olive oil while blending until you achieve a smooth consistency.
