These sweet treats are typically made from a rich dough that is deep-fried until golden brown and then dusted with powdered sugar. The name "Fasnachtswäggli" translates to "carnival rolls," reflecting their association with festive celebrations. They are often shaped into various forms, such as spirals or knots, and are a popular snack during the lively parades and events that characterize the Fasnacht festivities.
