Cook pasta (spaghetti is best), fry a little chopped bacon or pancetta. Beat eggs (1 per person) with a little creme fraiche, salt + prepper and grated parmesan or pecorino (optional), drain pasta, pour in egg mixture, stir through, add bacon, stir through again until the egg is cooked through. Serve with extra shavings of parmesan on top and freshly ground black pepper.
