@SinkGirl sorry, I've only just seen your request, I'm happy to share. I'm perhaps risking the wrath of our Italian members, but this is how I make it:
Spaghetti Carbonara
Serves 2
250g spaghetti
150g cubed pancetta
1 tbsp garlic oil (my cheat - by all means use normal olive oil and add some crushed garlic instead)
3 egg yolks
1 large handful grated Parmesan, plus extra to serve
Salt and pepper
Cook the pasta until al dente. When it is cooked, scoop out half a mug of cooking water and reserve.
Meanwhile, fry the pancetta in the garlic oil until starting to crisp.
Drain the pasta and return to the pan, off the heat. Working quickly, add the egg yolks and mix through the pasta, then add the pancetta and all the oil in the frying pan (it should still be sizzling as you add it), then the Parmesan. Stir well. Add enough of the reserved cooking water for the sauce to turn creamy, mixing as you do. You won’t need all of it, but probably more than you think. It should be the consistency of single cream.
Serve with the extra cheese on top.
If you’re making this for more/fewer people, double or halve the quantities as necessary except the egg yolks - use one per person plus one extra. So, if you’re making it for 1, use 2 yolks. However - I find it hard to make for more than 2 people, because of volume of pasta - I tend to find I don’t have room in the pan.
