Lau Chingri is Bottle Gourd Vegetable with Shrimp combination. This is a Bengali Dish. Lau mean Bottle Gourd and Chingri means shrimps.
Most people find Bottle Gourd curry little boring as it doesn't have any taste and flavor of its own. However, according to my Bengali friends, Bottle Gourd and shrimp combination goes really well. So do try it at home and enjoy the video.
