The method of steaming food was invented during the Han Dynasty thousands of years ago. Legend has it that General Han Xin made cooking utensils from bamboo and wood to cook food with steam. Through history, steaming has evolved to be one of the most iconic and essential cooking techniques in the Chinese culinary lexicon. The steamer basket replaces the traditional bamboo base with terracotta. This natural material has efficient liquid absorbing characteristics, meaning it can absorb any excess moisture generated during steaming, ensuring that the food is perfectly moist. The steamer pot and lid in this Steamer Set are made from fireproof ceramic, which has excellent heat resistance compared to regular stoneware, making it less likely to crack at higher temperatures. The Jia steamer pot can be used on open flame gas stoves and in both conventional and microwave ovens.
