Spaghetti Carbonara with Arugula

Make sure the skillet is warm but not hot when you add the eggs or they will cook or curdle before coating the pasta.

If the sauce doesn’t appear to be thickening because your skillet or ingredients are cool, heat the skillet over very low heat while stirring constantly.
