What to keep in mind.
5 tips from the recipe — small details that make a real difference to the final dish.
- 1Always use freshly grated Parmesan from a block. Pre-shredded cheese contains anti-caking agents that prevent it from melting smoothly, resulting in a grainy sauce.
- 2The starchy pasta water is liquid gold. It helps emulsify the sauce, making it creamy and helping it cling to the pasta.
- 3Do not overheat the sauce after adding the cheese. High heat can cause the dairy to separate and the sauce to break.
- 4If using frozen crawfish tails, make sure they are completely thawed and patted dry before adding them to the sauce to avoid watering it down.
- 5For a deeper flavor, deglaze the pan with a splash of dry white wine or sherry after cooking the garlic and before adding the cream.
