Kootstertille
Kootstertille is a traditional Dutch dish that has gained popularity in various parts of the world, particularly in the United States. The dish consists of a large, round, deep-fried doughnut, typically about 10-12 inches in diameter, filled with a sweet, creamy mixture of vanilla custard, whipped cream, and often topped with a layer of caramel sauce. The name "kootstertille" is derived from the Dutch words "koot" meaning "knot" or "ball," and "stert" meaning "tail," referring to the doughnut's shape and the way it is often served with a long, thin strip of doughnut attached to it.
The origins of kootstertille are unclear, but it is believed to have been created in the Netherlands
Despite its popularity, kootstertille is not widely available outside of Dutch bakeries and specialty food stores.
