Turn off your pan and leave it there as you want to keep the pan nice and hot
When the pasta is al dente (still a little firm, not mushy), use tongs to move it to the bowl with the pancetta. Move the pasta from the pot to the bowl quickly, as you want the pasta to be hot. It’s the heat of the pasta that will heat the eggs sufficiently to create a creamy sauce.
Add 1 full spoon of pasta water to your sauce mixture and mix it again
Turn on the pan again but very low
Add a little pasta water to the pan
Toss everything to combine. Mix it fast so the eggs won’t scramble, the water will help to avoid it scrambling
Keep mixing and when you see the watery sauce become a cream it is ready to serve (will take a few minutes)
Enjoy and serve straight away
