3. Discard any mussels that haven't opened.
4. Add the calamari rings and the shrimp and keep sauteing until the shrimp turns orange in color.
5. Deglaze with the white wine and add the tomato sauce and the herbs.
6. Reduce the sauce slightly and add the cream.
7. In the meantime, bring 4 litres of water to a rolling boil, add some sea salt and boil the fettuccine until al-dente (usually about 10 minutes) stirring ocassionally so they don't stick to each other.
8. Strain the fettuccine and toss them in the pan with the sauce.
9. Stir well, season with salt and pepper to taste and serve the seafood fettuccine in four pasta bowls.
Cooking tip: For a lighter pasta you can use 18% cream instead of the heavy cream.
Also, you can add a few dashes of oyster sauce for a stronger seafood taste to the pasta.
