Preheat the oven to 200 degrees F. Line a baking sheet with parchment paper. Using a small glass and a pencil, draw 6 (2 1/2-inch) circles on the parchment. Turn the paper face down on the baking sheets.
Beat the egg whites, cream of tartar, and salt on high speed until soft peaks form. Add the vanilla, then gradually add the sugar and beat on high speed until the egg whites form very stiff peaks.
With a large star - shaped pastry tip, pipe a disk of meringue inside each circle. Pipe another layer around the edge to form the sides of the shells.
Bake for 2 hours, or until the meringues are dry and crisp but not browned. Turn off the heat and allow the meringues to sit in the oven for 2 hours or overnight.
Slice strawberries and sprinkle with sugar. Let sit for 30 minutes to draw out the juices. Mash a couple berries if needed to help the process.
To assemble schaum tortes, top each meringue cup with a scoop of ice cream, then top with the berries and juices, then whipped cream.
