I've cooked this quick and simple dish for years and referred to it as Carbonara, but if you want to be pedantic, and many people do, it's not a traditional Carbonara. As I understand it, it would not traditionally contain cream. I'm all for respecting tradition, but this recipe is so popular with my family, that I shall continue to incorporate cream into the dish, but will not claim it's pasta carbonara.
Ingredients
1 pack of lardons or pancetta cubes
3 eggs
Handful of freshly grated parmesan
Double cream 60 to 80ml
Grind of black pepper
Pasta for 2 people
Method
Place the lardons in a dry, non-stick pan over a medium heat. As the fat on the lardons heats up, it liquifies and cooks the meat. When cooked to a deep colour and crisp, remove from the heat and save for later.

Start cooking the pasta.
Break the eggs into a bowl and add the parmesan, cream and a grind of pepper, then mix together with a fork.
When cooked, drain the pasta and return to its, still hot, saucepan. Add the creamy muixture and the reserved crispy lardons and stir over a medium heat. In a traditional carbonara the sauce would cook in the heat of the cooked pasta, but we need heat here to thicken what is effectively a bacon and parmesan custard. Keep stirring until the sauce thickens and clings nicely to the pasta.
Serve into warmed pasta bowls and consume greedily with a glass of robust white wine.
