To a cold pan add your cubed guanciale. Turn heat to medium and cook, stirring often for 6-8 minutes or until brown and crispy. Remove guanciale with a slotted spoon and save the fat.
To a frying pan over medium high heat, add your peppercorns and toast tossing often for 2-3 minutes or until fragrant. Transfer to a mortar and grind until a fine powder. Set aside.
To a bowl, add egg yolks, grated cheese, 1 Tbsp guanciale fat, and a pinch of the toasted pepper. Mix until a thick paste.
To a pot of boiling water, add your pasta and cook to package directions. Make sure to save some pasta water!
In a double-boiler, add your cooked pasta and the egg mixture. While mixing vigorously, slowly add your pasta water until a creamy sauce forms. Add your guanciale and mix until evenly distributed. Serve a generous portion on a plate and top with more guanciale, freshly grated parmesan cheese and enjoy!
