Add 4 cups fish, vegetable or chicken stock to a medium sauce pan, bring the stock to a simmer, then reduce heat to low.
Pre heat oven to 150 ℉ and place serving plates on the middle rack of the oven to warm.
Heat 3 tbsp olive oil a medium sized stock pot over medium heat for 1-2 minutes. Add 3 large shallots finely diced and sauté the shallots until they are soft, but not browned, about 5 minutes. Add 1 clove grated garlic to the shallots and sauté for one minute or until fragrant.
Reduce heat to medium low and add 1 1/2 cups good Arborio rice. Stir to combine, making sure that the rice has been fully coated in olive oil.
Add 1/2 cup white wine and stir to combine. Simmer until the wine has been reduced by about 3/4.
Add stock to the rice to barely cover the rice. Stir occassionally until the liquid has been fully absorbed, about 4-5 minutes with each addition of stock. Continue to add stock to the rice until each addition has been fully absorbed but make sure that the amount of stock you add is always just enough to barely cover the rice. Continue to add stock until the rice looks creamy or until you have added all the stock. If the rice looks a bit dry, add more stock a little at a time. Add the chopped tomatoes and season with 1 tsp Cajun Spice Mix, 1 tsp Hungarian paprika and kosher salt and freshly ground black pepper. Stir to combine and reduce heat to medium low.
When the tomatoes and seasoning have been fully blended, add 12 large (13-15 count/lb) shrimp, cleaned and tails removed, and stir to combine with the rice. Cover pan and cook for 2-3 minutes or until the shrimp have turned pink.
When the shrimp have turned pink, remove to a plate and 1 tbsp unsalted butter to the risotto, gently stir to combine.
