1. Prep the rice. If your rice is freshly cooked and still warm, spread it out on a baking sheet for at least ten minutes to release steam and dry slightly. Cold day-old rice works best but any chilled rice will do — just break up clumps with a fork so you get even distribution in the wok or skillet.
2. Make the sauce mixture. In a small bowl, whisk together the fish sauce, dark soy sauce, light soy sauce, sugar, and white pepper until the sugar dissolves completely. Set aside while you cook.
3. Cook the aromatics. Heat 1 tablespoon of oil in a large wok or heavy skillet over medium-high heat. Add the shallots and cook for about one minute until they soften and turn translucent, then stir in the garlic and red curry paste — cooking them together for another thirty seconds until fragrant but not burned (curry paste burns quickly).
4. Scramble the eggs. Push everything to one side of your wok/skillet and add the remaining tablespoon of oil to the empty space. Pour in the beaten eggs and let them sit undisturbed for about fifteen seconds, then gently scramble with a spatula until they're just set but still slightly soft — you want curds, not a solid omelet.
5. Fry the rice. Add your thawed peas and carrots to the wok along with the chilled rice. Break up any remaining clumps with your spatula as you stir-fry everything together for about two minutes until the rice starts to separate nicely. You should be able to see individual grains moving freely now rather than sticking together in globs.
6. Add sauce and finish. Pour the prepared sauce mixture evenly over the rice and toss continuously for another minute or two, making sure every grain gets coated. The rice will absorb most of the liquid — if it looks too dry after thirty seconds, add a splash more water or broth. Taste and adjust seasoning; you want it savory with just enough sweetness to balance the saltiness from the fish sauce.
7. Serve immediately. Transfer to serving bowls or plates and garnish generously with green onions, lime wedges on the side, and optional cilantro and crushed nuts. Squeeze fresh lime juice over each portion right before eating — this brightens everything up significantly.
