You can add either soft sugar or white granulated sugar to the scrambled eggs with tomatoes. There is not much difference in taste. In fact, if possible, it is more recommended to add rock sugar. Because rock sugar has a certain fire-reducing effect and tastes sweet but not greasy, you don’t have to worry about it not melting when you put it in for frying. Generally speaking, adding rock sugar to tomatoes and scrambled eggs has a better taste and effect.
