Cheese – Pesto is often made with a combination of Parmigiano and Pecorino, although some make it with just Parmigiano or just Pecorino. You could try different variations (just Parmigiano, just Pecorino, or a mix of Pecorino and Parmigiano) to decide which one you like the best. I tried all these combinations, and they’re all delicious. Whichever one you get, don’t get the pre-grated cheese. Get a block of it and grate it at home.
