In a soup pot, melt the butter over medium heat until melted and frothy. Add the shrimp shells and mash them with a spoon for 2-3 minutes until fragrant. Season with salt, pepper, and crushed red pepper. Pour in the water. Once the water begins to barely boil, reduce heat and simmer, uncovered, for 25 to 30 minutes. Strain through a fine mesh sieve into a bowl and discard the shrimp shells. Carefully wipe out the soup pot and return to the stove.

Cover the tomatoes with water in a medium pot. Bring to a boil. Once the skins begin to split, transfer them to an ice bath. Once the tomatoes are cool enough to handle, peel and discard the skins. Transfer to a bowl and crush them with your hands.

Heat the neutral cooking oil in the soup pot over medium heat until hot. Add the shallot and cook for 2-3 minutes until beginning to turn golden brown and soften. Add the garlic and cook for 45 seconds until fragrant. Add the tomatoes, beans, and reserved shrimp stock (you might need to discard like half a cup, of the stock depending on how full the pot is). Bring to a low boil and season with the paprika, smoked paprika, the Amarillo paste, and more crushed red pepper if you want it a bit spicier. Taste and add a bit more salt and pepper, if needed. Cook over a low boil 10-15 minutes to allow the flavors to meld.

During the last 10 minutes of the broth cooking, prep the shrimp. Take out half of the peeled shrimp and cut them into thirds.

Add all the shrimp to the pot along with the cream and parsley. Cook for 5-7 minutes or until the shrimp are opaque but not overcooked.

Ladle the shrimp soup into bowls and garnish with a drizzle of extra virgin olive oil and more finely chopped parsley, if desired. Enjoy!
