Season a large pot of water with salt and bring to a boil. Get your pasta cooking when you start cooking your bacon. MAKE SURE TO SAVE SOME PASTA WATER FOR SAUCE. In a frying pan over medium heat, toast your peppercorns until fragrant. Then grind them. In a bowl, mix cheese, eggs, and pepper. In a cold frying pan, add sliced bacon and turn the heat to medium. Once the bacon is crispy and fat is rendered (around 8-10 minutes), add cooked pasta and cheese mixture. Mix vigorously and add a small splash of pasta water as needed. Once the sauce is emulsified, plate and enjoy!
