Chef’s Tips
-
Always add egg yolks off the heat to prevent curdling.
-
Use freshly grated Parmesan for the best flavor and texture.
-
Taste and adjust seasoning just before serving.
Storage
Leftovers keep for up to 2 days in an airtight container in the refrigerator.
Reheat gently over low heat with a splash of cream or pasta water. Avoid microwaving to prevent a grainy sauce.
Variations
-
Vegetarian: Replace ham with sautéed zucchini, mushrooms, or sun-dried tomatoes.
-
Protein swap: Use bacon lardons or shredded roast chicken.
-
Cheese alternative: Try Grana Padano or Pecorino for a sharper flavor.
