People follow certain rules and regulations while eating. It includes warm hospitality and particular ways of serving as well. This is known as Bangaliketa (বাঙালি কেতা). The culture also defines the way to invite people to weddings and for dinner. Gifts are given on certain occasions. Bangaliketa also includes the presentation of serving utensils in a proper manner. This has led Bangladeshi cuisine to include many rich aromatic dishes such as biriyani and korma that requires the use of a large array of spices along with an extensive amount of ghee. Dhaka being the Mughal capital of the Bengal Subah (which includes modern Bangladesh and the Indian states of West Bengal) was a major trading center in South Asia, so many culinary styles from around the world influenced the city's cuisine. After Dhaka became the capital of East Bengal, the Bangladeshi populace began to adopt the cuisine of the city with many Persian, Turkish, and Arabic-influenced dishes becoming popular.
