The dish Haleem is popular in India, Middle East and other parts of Asia. Haleem originates from an 10th century Arabinan dish callled as Harees. This dish, Harees was brought into India by the Nizam (Hyderbad) Army. Restaurants in the old quarter of Barkas in Hyderabad, still serve the original dish of Harees
It is a thick aromatic curry or stew like dish that contains meat, lentils and spices. This slowly cooked dish over few hours is rich in calories and nutrition, that is popular among the Muslims while they break the fast during Ramzan. Hence the incidental association.
Many mouth watering dishes, sweets and lassi is sold in the popular streets of Bangalore, during Ramzan. I think, after a long period of fasting, people would anticipate to have rich, tasty food.
