Over medium heat in a large, deep sided sauté pan, render bacon until crispy on all sides. Once bacon is crisp, turn the heat as low as it can go. Spoon out all but about 3 tablespoons of bacon fat.
While the bacon is rendering, begin heating the amount of pasta water directed on the box, adding enough salt added to make the water as salty as the ocean, at least a tablespoon.
While the pasta water is coming to a boil, beat the eggs and egg yolks together in a 2 cup liquid measuring cup with a spout for easy pouring, until they are homogenous, then stir the parmesan cheese and black pepper.
Once the pasta water is boiling, add your pasta, cooking 1 minutes less than box instructions.
Do not drain the pasta. Add one ladle of pasta water to the bacon pan. Using tongs transfer the pasta from the pasta pot to the bacon pan. Toss the pasta in the bacon fat and pasta water until coated.
Slowly add 1/4 cup of the hot pasta water while stirring to the egg and parmesan mixture to temper the eggs.
While continuously and vigorously tossing the pasta with the tongs, begin slowly adding the parmesan egg mixture; keep tossing until the pasta is evenly coated in the parmesan egg mixture. Keep moving the pasta and begin adding additional pasta water ¼ cup at a time until the sauce develops a sheen and desired consistency.
Taste for seasoning, add additional salt and/or pepper if needed. Garnish with more parm and black pepper, serve immediately.
