The cuisine here has been shaped by the natural bounty of the surroundings and the traditional practices of the local ethnic groups. Ingredients like freshwater fish, tropical fruits, local vegetables, and herbs are staples. Due to its remote nature, the influence of foreign cuisine is less prominent here compared to other parts of Cambodia, maintaining a more authentic and traditional culinary culture centered around local produce and community-driven cooking methods.
