Pat shrimp dry and season with salt and pepper. Then cook the pasta with salt 8-10 mins (make sure to reserve 1/2 cup of that starchy pasta water when done).

Cook shrimp on medium high 2 mins on each side while pasta is boiling. When done, add garlic and shallot and continue cooking for about a minute. Then add spinach until wilted. Lower heat to medium.

Add cream, parmesan, base, and pasta water. Cook until desired thickness is reached. Add pasta and done.
