Yangzhou fried rice from Jiangsu Province is the most famous variety of fried rice in China. Known for the fine knifework in cutting the ingredients, it has been the model for “special fried rice” or "house fried rice" dishes found on Chinese restaurant menus in the West.
The ingredients added can vary greatly but the key is the careful preparation of ingredients. You can use rice cooked in chicken stock if you want an even more flavourful result.
The patron of an excellent restaurant in China once told me that the secret to a really good fried rice is finding a really good chicken, and really the origins of fried rice celebrate the connection between chicken and rice. The rice is cooked in chicken stock (less common these days, as chicken powder is often used), some of the chicken meat and offal is used as an ingredient, and then egg is mixed with the rice.
Almost all fried rice recipes around the world still use a combination of chicken, egg and rice.
