A chalupa shell is a type of fried bread that is thicker than traditional corn or flour taco shells. It is boat-shaped and crispy on the outside while soft on the inside. The shell is made from a dough that is comprised of flour, butter, milk, salt, and baking powder. The dough is shaped into a long cylinder, cut into eight equal parts, and then rolled into a round circle about six inches across. The disks are then fried in oil until they are crispy and golden brown. Once the shells are cooked, they can be filled with various taco toppings such as ground beef, shredded chicken, lettuce, cheese, and tomatoes.
