Spaghetti carbonara is cheap and delicious. A true Italian one has no cream!
A good, economical approximation is the following.
For each (adult size) serving: 100g or 4 oz spaghetti, 1whole egg, 1-2 oz Parmesan or Pecorino or to taste, salt, pepper, red pepper flakes, 2-3 streaky rashers. EVOO.
Saute the rashers in a large enough pan to hold the pasta, in a bit of EVOO. Don’t drain the pan. Tear the rashers into pieces about 1inch square.
Beat the eggs, grate the cheese and mix these. Season with S&P. Add hot pepper flakes if you like.
Meanwhile cook the spaghetti, reserving a cup of the pasta water. Warm the bacon drippings in the saute pan and toss the pasta in the hot drippings. Add EVOO if necessary until the strands glisten. Turn off the heat, add the egg mixture and toss. It probably isn’t silky - add pasta water by the tablespoonful, tossing, until a silky texture is obtained. Add the bacon bits and more black pepper if necessary and toss one last time. Serve quickly.
