01 - In a small bowl, steep the saffron threads in 2 tablespoons of the warmed stock and set aside.
02 - Heat olive oil in a 10-11 inch paella pan or wide skillet over medium heat. Add the onion and red bell pepper, sautéing for 3-4 minutes until softened.
03 - Stir in minced garlic and smoked paprika, cooking for 30 seconds. Add the grated tomato and cook for 2-3 minutes until most of the liquid evaporates.
04 - Add the rice to the pan, stirring constantly for 1 minute to coat each grain with the oil and aromatics.
05 - Pour in the saffron-infused stock, remaining stock, and bay leaf. Season with salt and pepper. Bring to a gentle simmer without stirring from this point forward.
06 - Distribute the calamari rings, shrimp, mussels, and clams evenly over the rice surface.
07 - Cook uncovered over medium-low heat for 15-18 minutes, gently shaking the pan occasionally to prevent sticking but maintaining the integrity of the rice.
08 - Scatter peas over the top and continue cooking until the rice is al dente, seafood is fully cooked, and most liquid is absorbed, approximately 8-10 minutes.
09 - Remove from heat, cover the pan with a clean kitchen towel, and let rest for 5 minutes to allow flavors to integrate.
10 - Discard any mussels or clams that have not opened. Garnish generously with chopped fresh parsley and serve immediately with lemon wedges.
