Dust the shrimp with a generous amount of Old Bay and set aside.
Cut the into bacon into lardons.
Place egg, yolk, and fresh ground black pepper in a large bowl. Whisk to combine.
Grate your cheese using a microplane grater and set aside. DO NOT use pre-shredded cheese as it will not melt properly.
Bring 4 litres/4 quarts of water to the boil with the salt. Add pasta and cook per the packet directions.
Just before draining the pasta, scoop out 1 cup of pasta cooking water and set aside.
While the pasta is cooking, render the bacon until crispy.
Add the shrimp and saute until just cooked through.
Add the garlic and stir to mix in.
Add the drained hot pasta into the pan and toss to coat.
Whisk the grated cheese in the egg.
Add the pasta mixture into the bowl with the egg.
Add 1/4 cup (or so) of the pasta cooking water. Stir vigorously for 1 minute and the sauce will transform from watery to creamy and clings to the pasta strands! Add a bit more watery if needed.
Serve immediately, garnishing with a bit more cheese.
