Puzzle Eurographics: 1000 piece Donut party

Doughnuts are usually deep fried from a flour dough, and typically either ring-shaped or a number of shapes without a hole, and often filled, but can also be ball-shaped ("doughnut holes"). Other types of batters can also be used, and various toppings and flavorings are used for different types, such as sugar, chocolate, or maple glazing. Doughnuts may also include water, leavening, eggs, milk, sugar, oil, shortening, and natural or artificial flavors.
