Boil water for pasta, adding salt.
Cut pancetta into cubes or rectangular pieces.
Grate Pecorino. Add grated cheese into a bowl with two eggs and one egg yolk.
Mix eggs and cheese together, adding about 1 teaspoon of black pepper.
Fry pancetta.
When pancetta is nearly done, add the pasta to the boiling water and cook according to al dente instructions, about 6 minutes. When pancetta is done, remove the pan from heat.
When pasta is al dente, quickly transfer it to the pancetta pan. Do not drain or rinse the pasta. Then, quickly pour in the egg and cheese mixture.
Stir the pancetta, pasta and egg mixture continuously until it forms a creamy sauce. Be careful not to keep your pan on the heat because that could result in scrambled egg-type mixture. If you need a bit more creaminess for your pasta, add some of the pasta water, which has starch.
Serve pasta carbonara immediately, topping with more black pepper.
