Bring a pan of water to the boil. Add rice, a good pinch of salt and stir. Reduce heat, cover and simmer for 20 minutes.
When cooked, put to one side and allow the rice to cool fully.
Heat a wok for 2 minutes. When the wok is hot, pour in vegetable oil, frozen peas and onions. Mix well and cook for 3 minutes.
Mix in cold rice and shrimp and cook for about 3 minutes. Continue to stir constantly.
Mix in spring onions, eggs, salt, pepper, oyster sauce, soy sauce and sesame oil together with the diced cooked ham.
Cook for another 4 minutes, stirring until the eggs are cooked and everything is mixed evenly.
Notes
Notes: Always cook the rice in advance and allow to cool. Doing this will prevent the rice from sticking when reheating. The Ham should also be cooked in advance.
