Dum aloo, also called alu dum, is a traditional dish with origins in Kashmir. The dish consists of potatoes, tomatoes, and onions that are cooked together in curry or masala sauce. It is said that cooking dum aloo is an art because it needs to be boiled and fried just right, the spices need to be authentic, and it takes a lot of time and patience to prepare it.
Dum aloo is cooked over low heat in a traditional earthenware vessel (handi) that is usually sealed until the dish is ready to be consumed. Its name is a combination of the words aloo (potatoes) and dum (steam, or warm breath).
