Here's a by-the-seat-of-your-pants recipe for some very good pasta. Myzithra is a greek cheese made from Sheep milk with a similar texture to Parmesan, it's a very hard cheese with a sharp salty tang. You only need 3 ingredients for this dish: pasta, butter and Myzithra.
Cook enough pasta for how every many you are cooking for. Slowly melt some butter, probably a few tablespoons for each person. (You can always melt more later if needed.) Grate the cheese using the smallest holes on the grater. When the pasta is cooked, drain it and return to the pot. Add the butter, trying to leave the milky solids in the pan. Toss the pasta and butter until the pasta is coated.
What you do next is up to you. You can either add the cheese to the pot and mix together, or do what we do. We plate the pasta, then add the cheese so each person can add how much they want.
Whichever you do, don't forget to grind some pepper on your pasta before you eat.
