Prep everything before you start cooking — fried rice moves fast. Mince the 3 cloves ajo picado, slice the 3 stalks cebolletas cortadas en rodajas finas, partes blancas y verdes separadas (keeping white and green parts separate), thaw the Peas and Carrots, beat the 3 huevos ligeramente batidos, and break up any clumps in your cold Long-Grain White Rice with your hands or a fork.

In a Mixing Bowl, stir together the 3 tbsp salsa de soja, 1 tbsp salsa de ostras (if using), 1 tsp aceite de sésamo tostado, and ½ tsp pimienta blanca. Set aside.

Heat a Wok or Skillet over high heat until it just begins to smoke. Add 1 tablespoon of 2 tbsp aceite vegetal dividido and swirl to coat. Add the beaten 3 huevos ligeramente batidos and scramble quickly, breaking them into small pieces. Remove the 3 huevos ligeramente batidos to a plate before they are fully set — they will finish cooking later. Set aside.

Return the Wok to high heat and add the remaining 1 tablespoon of 2 tbsp aceite vegetal dividido. Add the white parts of the 3 stalks cebolletas cortadas en rodajas finas, partes blancas y verdes separadas and the minced 3 cloves ajo picado. Stir-fry for about 30 seconds until fragrant — do not let the 3 cloves ajo picado burn.

Add the Peas and Carrots and stir-fry for 1 minute until heated through.

Add the cold Long-Grain White Rice to the Wok. Using a Spatula, press and toss the 4 cups arroz blanco de grano largo cocido, de un día anterior y frío, grumos desmenuzados against the hot surface, breaking up any remaining clumps. Stir-fry for 3–4 minutes, letting the 4 cups arroz blanco de grano largo cocido, de un día anterior y frío, grumos desmenuzados sit undisturbed for 30 seconds at a time between tosses so it can get a little toasty.

Pour the sauce mixture evenly over the 4 cups arroz blanco de grano largo cocido, de un día anterior y frío, grumos desmenuzados. Toss well to coat every grain. Stir-fry for another 1–2 minutes until the sauce is fully absorbed and the 4 cups arroz blanco de grano largo cocido, de un día anterior y frío, grumos desmenuzados looks glossy.

Return the scrambled 3 huevos ligeramente batidos to the Wok and fold them into the 4 cups arroz blanco de grano largo cocido, de un día anterior y frío, grumos desmenuzados, breaking them into smaller bits as you go. Taste and adjust with ½ tsp sal if needed.

Remove from heat. Garnish with the green parts of the sliced 3 stalks cebolletas cortadas en rodajas finas, partes blancas y verdes separadas and serve immediately.
