How to Make Spanish Windtorte

To Make the Filling: In a large bowl or stand mixer, whip the heavy cream and confectioners' sugar until it starts to thicken. Add the liquor, if using, and whip hard to compensate for any moisture from the berries. Fold in the berries and fill the meringue shell. Place the top on and serve immediately.

When ready to serve, remove the top and slice pieces as you would for a cake. The meringue will probably splinter, but that, also, is to be expected.
