Wok-fried rice with eggs, carrot, onion, green onions, peas, garlic, ginger, soy sauce, butter, and peanut oil. The rice is pushed until properly charred for smoky fried-rice flavor.

Heat a wok or wide pan until very hot. Scramble the eggs first (fast, soft), then set aside.
Add peanut oil. Fry carrot and onion, then add green onion whites and peas. Stir-fry briefly until warm. Add garlic and ginger and cook for ~30 seconds.
Add the cold cooked rice. Spread it out and press it into the pan in an even layer. Leave it to toast and burn slightly for smoky fried-rice flavor (not just steaming).
Season: pour in soy sauce and rice vinegar. Add sugar and butter; let them melt and sizzle so the rice gets glossy.
Toss everything together to evenly coat the rice. Add back the scrambled eggs and stir until heated through.
Finish with green onion greens. Taste and add salt if needed. Serve hot.
