So do what you can, but don’t add ingredients that have nothing to do with the authentic recipe (we’ve noticed this in many recipes) such as ricotta cheese, cashew nuts, seeds oil, green beans or lemon juice.

Step 4: Add the basil leaves while continuing to gently crush, then add the two grated cheeses and mix everything together.
Step 5: Soften the mixture by slowly pouring the oil until you have a homogeneous, creamy consistency, then transfer it to a bowl and finish mixing it with the remaining oil.
1 – You must never step on the leaves with force, but gently rotate the pestle along the walls of the mortar, so as to tear them up without cutting them.
2 – The processing must take place at room temperature and not take too long, to avoid oxidation which alters the flavor and color of the basil.
3 – The quantity of garlic can be reduced or increased according to personal taste, but the total lack alters the original taste.
4 – Some make an addition of walnuts, tolerable variant, but cashews, parsley and lemon must be avoided.
