Henan cuisine, also known as (Yuyan) 1, is the Central Plains (Henan) cuisine 2. It is a general term for dishes, noodles and banquets made by using the techniques and materials with the regional characteristics of the Central Plains under the guidance of the cooking theory with the traditional cultural connotation of the Central Plains. Yi Yin, known as "the originator of cooking" and "the ancestor of Chinese chefs", was born in Henan (Yichuan in Luoyang, Kongsang in Qixian in Kaifeng). Contemporary Henan cuisine has gradually accumulated and evolved on the basis of the original palace cuisine, official cuisine, local cuisine and folk cuisine, according to the material conditions of the Central Plains. Premier Zhou Enlai personally decided to use "Henan cuisine" as the national banquet, with Henan chefs as the chef.
