The area surrounding the Nalian Forest Office in Khulna is rich in both cultural heritage and biodiversity, which is reflected in the local cuisine. Historically, this region's food has been influenced by the forests, rivers, and the Sundarbans, the largest mangrove forest in the world. The cuisine here has been shaped by the availability of fresh fish and a variety of rice. Vegetarian dishes also hold significance due to the agricultural practices in the region. The food has evolved to be a mix of traditional Bengali flavors with an emphasis on fresh ingredients, spices, and the use of mustard oil which is a staple in Bengali cooking.
