Delicious pasta recipe! The sauce is a little on the salty side so don't pour too much sauce on the pasta at once - add to taste. The saltiness, though, is perfect for the thickness of the fettuccine noodles. I added 1/2 a tbsp of minced garlic and a dash of cayenne pepper instead of white pepper to the sauce. Separately, we brined the raw shrimp and scallop in kosher salt water for a few minutes then sauteed the shrimp and scallop in a little bit of olive oil, butter, garlic, and some old bay seasoning with chopped green onions. We later added the sauteed shrimp and scallop mix to the sauce. As other reviewers have noted, if you do not like pepper, this is not for you. My family loves spicy, peppery foods, so this was delicious. The red pepper flakes added the perfect kick.
