Submerge 8 large frozen shrimp in a large bowl of cold water until fully thawed, drain and pat dry with kitchen paper. (Skip this step if you are using fresh shrimp.) Cut each shrimp into 3 pieces. Set aside.
Crack 3 large eggs in a bow, whisk until well combined. Chop 1 green onion. Peel a pomelo, get about ½ cup of pomelo flesh.
Place 2 cups of cold cooked rice in a bowl, place an ice cube on top of the rice, cover with a piece of parchment paper. Microwave on power 100% for 1 minute if it's refrigerated rice, for 2 minutes if it's frozen rice.
Remove the parchment paper and the ice cube. Loosen the rice grains with your hands. Add 2 tbsps of light soy sauce and 1 tsp of sesame oil (*note it's tsp here, not tbsp) to the rice, mix with your hands until well combined.
Heat up a nonstick frying pan/wok over high heat for 2 minutes, add 1 tbsp of vegetable oil to the pan, heat up the oil for 30 seconds. Pour the eggs to the pan, quickly stir-fry for about 30 seconds until the eggs are just set. Transfer fried eggs to a bowl.
No need wash or wipe the pan, add 1 tbsp of vegetable oil to the pan. Add the shrimp to stir fry over medium high heat for 1 minute, add the frozen vegetables to stir fry over medium high heat for 2 minute.
Add the rice to the pan, stir fry over medium high heat for 2 minute.
Add fried eggs, 1 tbsp of soy sauce, 1 tbsp of oyster sauce, ½ tbsp of sugar, ¼ tsp of Szechuan pepper powder, and ¼ tsp of salt (gradually add to your taste), stir fry over medium high heat for 2 minute until all the ingredients are evenly heated and well combined.
Turn off the heat, add ½ cup of pomelo flesh and chopped green onion to the fried rice. Stir to combine, then quickly transfer to a serving plate (pomelo flesh will taste bitter if it's heated for too long).
Serve hot. To store: keep in an airtight container in the fridge for up to 3 days or in the freezer for up to 3 months. Reheat with the ice cube parchment microwave method that I have just used above.
