I remember cooking bacon carbonara for my agents on shift last  Christmas and New Year. Well, I can't remember a recipe unless I cooked  it again.
1 pack 250g spaghetti
1 can nestle creme (300g/10.5oz) or 2 packs all purpose cream (250 ml)
1/4 kilo bacon, chopped
4 drops of tabasco
1/2 cup of grated cheese
1 egg yolk
Cook spaghetti noodles as per instructions. Drain well.  
While cooking noodles, chop bacon into 1/2 inch length or to length  desired.  Once bacon is cooked (I don't like my bacons toasted, just  cooked), turn off heat. Add cream, cheese, egg yolk and tabasco.  The  tabasco won't make the pasta spicy, it'll add a different kind of spice  to it, so don't put too much tabasco. Add spaghetti and mix well. Serve  hot.
