  • It's important not to drain the pasta, so the dish does not dry out.
  • Adding the jalapeno with the cheese keeps the pepper intact for a flavorful bite.
  • The liquid crab boil gives more heat and flavor but is not necessary.
  • Substitute 1 pound of peeled and deveined raw shrimp for the crawfish for a Shrimp Fettuccine.
