Soak rice with saffron for 1 hour in cold water to cover; drain.
Wash the chicken, pat dry with paper towels, and sprinkle with salt, pepper and lime juice.
In a large, heavy burner-and oven-safe casserole over medium heat, heat 2 tablespoons of the oil over low heat until it is fragrant, then brown the chicken 6 to 8 minutes on each side. Remove the chicken and set it aside. Add the remaining oil and cook the onion, bell pepper and garlic, stirring, until the onion is translucent, 6 to 8 minutes. Add the tomatoes, pimentos, cumin and bay leaf and cook, stirring, 5 minutes. Add the chicken, mix well, add the wine and cook 5 minutes.
Add the stock and bring to a boil. Adjust the seasonings, it should be somewhat salty, because the rice will absorb salt later on.
Preheat the oven to 350 degrees. Add the drained rice and, if it is not yet bright yellow, add the additional saffron. Bring it to a boil over high heat and cook, uncovered, stirring often, until most of the water has been absorbed and small craters form on top of the rice, 20 to 25 minutes.
Remove from the heat, add ¾ cup of the peas, cover, and place in the oven until the rice is tender, about 20 minutes. You can do this step on top of the stove over medium heat, but the rice cooks better and becomes more tender in the even heat of the oven. This is especially true if you double or triple the recipe to serve a large group.
