Put on a pot of lightly salted water over high heat to boil
While the water is coming to a boil, cook the pancetta over medium heat in a skillet
In a bowl, beat together the eggs, two cheeses, and a lot of freshly ground black pepper. Set aside.
As the pancetta becomes crispy, add the wine to the skillet and scrape up the tasty bits. Turn off the flame.
When the water comes to a boil, add the pasta and give it a stir so it completely submerges
Cook the pasta one minute less than shown on the package
Drain the pasta and return the pasta to the pot
While stirring the pasta, slowly add the egg & cheese mixture. Continue stirring for one minute. (See note below.)
While still stirring, add the cooked pancetta being sure to stir thoroughly
Serve and eat immediately
Notes
It's critical to add the egg and cheese mixture slowly while stirring the pasta rather vigorously. This will ensure that you get that lovely creamy coating on the pasta rather than ending up with noodles and scrambled eggs.
