Grand Hotel Cosmopolis

The Grandhotel Cosmopolis is preparing a vegan tart

A vegan recipe from the Cosmopolis collective, hosts of Grand Hotel Cosmopolis

The Grand Hotel Cosmopolis is much more than a normal hotel: the former old people's home in Augsburg's old town houses a state collective accommodation for 65 refugees, a hotel, a gastronomic establishment, an academy and offers plenty of space for art.

In order to protect the residents, guests, volunteers and employees, we had to close or cancel many areas, including the hotel, lobby / bar, lunch and events, until further notice in mid-March.

For the filling:

  • 5 to 6 onions; red, white or yellow
  • 4 tablespoons of grainy mustard

2. Knead the dough into a ball and chill for 30 minutes.

3. For the filling, cut the onions into rings and sauté them in a pan with a little oil. Add the chopped herbs at the end.
