Spaghetti Carbonara

You can, but the dish will taste different—guanciale has a distinctly funky, peppery flavor that defines carbonara. Pancetta is closer than bacon and will work in a pinch, but use the same weight and render it the same way.

The mixture was either too hot when mixed or left over direct heat. Keep the skillet off the stove after adding the guanciale, and stir the eggs constantly into the hot pasta away from direct heat so the residual warmth cooks them gently to a custard, not chunks.

Real carbonara never contains cream; eggs are safe when tempered by stirring constantly into hot pasta off the heat. If you add cream, it's no longer carbonara—it becomes a different, heavier dish that obscures the guanciale.

A crisp green salad dressed with lemon and olive oil, and crusty bread to wipe the plate. Avoid heavily sauced dishes; carbonara is rich enough on its own.

Carbonara must be eaten immediately after cooking; the sauce will not hold. Leftovers can be refrigerated for one day and reheated gently in a skillet with a splash of pasta water over low heat, stirring constantly, though texture will suffer.

Add reserved pasta water one tablespoon at a time while stirring—it contains starch that helps emulsify the sauce and restore flow without breaking the egg custard.
