Guanciale, which is unsmoked Italian bacon prepared with pig's jowl or cheeks. Fail to find that, use pancetta.. Or bacon would work too.
Put a pot of water on the fire
While you wait, crack the egg into a bowl. Use fresh eggs or you will meet our friend salmonella.
Grate parmigiano. You can always grate less
Cook enough for one person.. About one-hundred grams
Cook it for the time that says in the package. Or one minute less, if you like it al dente
Make sure you stir a little at the beginning so the strings don't stick together.
Get your blue strainer ready for action
Put a small pan on the fire
Add your pancetta and garlic and fry it together.
Put on top of the pot so it doesn't drip everywhere. Do this steps quickly so the pasta doesn't cool off.
Let it gain some temperature. Mix mix.
Add to your mixture and mix.
Who doesn't like extra cheese? See if it needs salt.
Ready for some lady and the tramp situation.

Eat a nectarine if it helps.
