A deep-dish apple dessert is a type of dessert that is made by layering apples in a deep dish and baking them with a topping such as a pastry crust or a streusel. The term 'pandowdy' is used to describe this type of dessert, which is believed to have originated in the United States in the 19th century. Pandowdy is an 8-letter word that is derived from the English dialect word 'pandy, ' which means 'to cut into small pieces.'
