Potti/Pooti Olarthiyathu refers to one of the dishes from Kerala, India which is stir-fry cow's intestines (Potti/Pooti). It is made from fresh and thoroughly cleaned cows/ goats or buffalos' intestines with lots of spices and curry leaves. It is usually served very spicy from chopped red chilies.
This picture is made from while the Potti/Pooti was still being cooked to be served for a pre-wedding dinner which is a tradition in Kerala. So much to cook for hundreds of relatives and friends invited for pre-wedding dinner party.
Olarthiyathu which means stir-frying is also spelled Olathiyathu and Ularthiyathu
Another version below of the Potti is not chopped intestines, but made from bigger slices so the intestines are stil recognizable
