What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Use freshly grated Parmesan—pre-shredded contains anti-caking agents that prevent smooth melting.
- 2Undercook the pasta by 1 minute; it will finish cooking in the hot sauce and stay al dente.
- 3Warm the crawfish tails gently—overcooking makes them rubbery and tough.
- 4Add pasta water a tablespoon at a time until the sauce clings to the noodles without being soupy.
- 5Let the sauce rest off the heat for 1 minute before serving—it will thicken slightly as it cools.
- 6Taste before adding extra salt—Creole seasoning and Parmesan are both salty.
