Spaghetti all'assassina

1: Peel shrimp and save the shells for the broth.

2: Marinate the shrimp in the listed ingredients.

3: Create the broth by mixing together tomato paste, bone broth (or just water), and water, seasoning with salt and pepper, and adding shrimp shells. Bring to a boil, boil for 5 minutes, and strain.

4: In a pan over medium-low heat, add olive oil, red chili flakes, Calabrian chilis, and garlic. Cook for one minute, being careful not to burn the garlic.

5: Add in the tomato purée and pasta. Cook until the bottom of the pasta begins to lightly char, adding tomato broth slowly until the pasta is al dente.

6: In another pan at medium heat, cook the shrimp with 1/4 stick of butter for one minute on each side.

7: Remove from heat and serve the pasta with the cooked shrimp.
