Start by pulsing 3 to 4 garlic cloves in the food processor to break them down. Or use a marbel ou wood mortar,I prefer, and smash the garlic cloves.Do the same thing with the others ingredients.

Take 3 large bunches of basil (that should be about 3 cups packed). If they’re not washed, well then wash them.Pluck the leaves off the stems, stuff them into the food processor, with about a 1/2 cup of pine nuts, about a 1/2 cup of grated pecorino cheese, and start pulsing. After the basil is fairly broken down, add about 3/4 to 1 whole cup of olive oil, depending on what kind of consistency you like, and continue pulsing until it becomes…pesto.

Add salt and pepper to taste, though pecorino cheese adds quite a bit of salt on its own.
