Here is one recipe from one of my books:
175g/6oz smoked streaky bacon, chopped
2 tbs sunflower oil
250g/8oz mushrooms, sliced
3 egg yolks, beaten
142ml/1/4 pint of single cream
4 tbs chopped parsley
1/4 teaspoon grated nutmeg
salt and pepper
Fry the bacon in the oil until crisp, then remove from the pan.
Drain all but 1 tbs fat from the pan, then fry the mushrooms until soft.
Cook spaghetti (recipe doesn't give quantities - but I would do at least 75g/30z per person), drain, return to the pan and then add the egg yolks and cream and mix well.
Mix in the bacon, mushrooms, parsley, nutmet and seasoning. Garnish with parley and serve with parmesan.
Quantities for 4, so just double.
I don't make mine like this, but as I haven't a clue about quantities, thought that any recipe would be better than none!
I would add a large handful or two of grated parmesan to the egg and cream. I also add finely chopped garlic to the bacon, as well as a slosh of white wine (which I then allow to cook off, so you're left with flavour but no moisture).
And I don't use mushrooms.
But good luck and hope you enjoy it whatever you do!!!
