filling
make it ahead Bake the crust and make the cashew cream the day before to save time during your party preparations. Store the crust tightly wrapped and the cashew cream in an airtight container in the refrigerator. Bring them out to sit at room temperature while you prepare the filling.
tidbits To make this suitable for Passover, substitute smoked salmon for the prosciutto.
If you can tolerate dairy, substitute crème fraîche for the cashew cream.
