Preheat oven to 250˚F. Line two sheet pans with parchment paper. With a Sharpie type permanent pen, trace 6 -3" circles on each sheet of parchment paper, and flip over in pan (marker side down).
Place in preheated oven and bake 1 hour, then turn heat off and leave Schaum Tortes in oven for another 30 minutes. Remove and store in an airtight container, or serve with fresh berries or ice cream.
Follow the first 4 steps as written. Then, transfer the meringue to a 9-inch buttered spring form pan. Bake at 250 degrees for 1 hour, turn off heat, and leave shell in the oven for 1 hour more (instead of 30 minutes).
