In a medium pan over medium-low heat, pour in ½ tablespoon olive oil. Add meat and garlic, tossing around to coat. We want the fat to render and the meat to eventually crisp so this is going to take a while. Be patient and/or start making dessert while you wait! (BLUEBERRY PIE COOKIE BARS are perfect to fill this hole...I mean time. Check on meat periodically. If it seems there's not a lot of fat rendering, lube up your meat with another ½ tablespoon of olive oil. When desired crispiness is achieved, remove meat and place on a paper towel-lined plate and drain grease into a small, heat-safe bowl. Set both aside for later. Discard garlic. About halfway through the rendering process, place a medium pot of well-salted water over high heat and bring to a boil.
Only after pancetta/bacon has crisped should you start boiling your pasta and making the carbonara sauce! So, 'LET'S GO, GIRLS!' ~ Shania Twain
Drop your pasta into boiling water and cook all the way though because it won't be cooking more in the sauce.
While pasta is boiling, grab a medium bowl. Add to it: whole egg, egg yolks, cheese, ground black pepper, and the rendered fat (max 2 Tbsp). Mix well.
Fill a medium (preferably metal) bowl with hot-ass tap water. Set aside.
When pasta is done to your liking, scoop out ¼ cup of the water and then drain the rest.
Dump hot water out of metal bowl and place spaghetti in there.
Pile on egg mixture and stir immediately. Add in pancetta/bacon and stir again.If consistency is too tight, add a bit of the reserved pasta water until you have the sauce you deserve. Taste and adjust with salt if needed. Serve immediately and top with more cheese and fresh cracked pepper if ya got it.
