The book, entitled “Cuisine Identities of Thang Long-Hanoi,” written by Dr. Nguyen Nha, head of the Institute of Vietnamese Cuisines.

The writer said he had to look up ancient documents and visit families who lived in Hanoi long ago for materials in his book.

In an effort to introduce the world to Vietnamese foods, the institute launched a programme called “Jointly prepare Vietnamese foods for the world.”

The programme featured courses for foreigners who want to learn how to cook Vietnamese dishes and Vietnamese people who plan to go overseas for work and study.

The institute also collaborates with enterprises sending Vietnamese cooking utensils and usage abroad.
