Rinse clams under cold water.
Place them in a large bowl, sprinkle with salt, and cover them with water.
Let them sit for 1 hour.
After about ½ an hour of this process you can get started on the rest of the dish.
Place saffron in bowl with ¼ cup hot water. Let sit for 15-20 minutes.
In large skillet or paella pan over medium-high heat, cook shrimp in 2 tablespoon olive oil until cooked, about 5 minutes.
Remove from pan and place on plate.
Add chorizo to pan and cook until browned, about 6-8 minutes.
Remove chorizo from pan and set aside with the shrimp.
To the same skillet, add 2 tablespoon olive oil, onion, red bell pepper, tomatoes, garlic, salt, and paprika. Cook, stirring often, until onions soften, about 6 minutes.
Add the saffron mixture (water and actual saffron), bay leaves, clam juice, and broth, and bring to a boil.
Add rice and peas, and stir to combine.
Lower heat to medium-low and cook without stirring 10-13 minutes, until the rice has absorbed most of the liquid.
Reduce heat to low and add in the shrimp and chorizo.
Place clams, hinged side down, in paella mixture. Cover pan and cook 10 minutes longer.
After 10 minutes, the clams should open.
Discard any that remain closed.
The authentic way of eating paella is straight from the pan so dig in!
