The production method is as follows:

First, pluck the oranges and remove the outside stems (white parts).

put the rock sugar in a steamer and boil it over high heat.

when the crystal sugar is melting, put in the orange, and after the water boils, simmer for about 1 minutes.

You can eat it when it is out of the pan and cooled. It is better to put it in the refrigerator with ice.
