1/2 cup dark roast coffee (decaf if desired), ground
4 cups water
1/3 cup sugar
4 oz. package bittersweet chocolate, broken into pieces
1/2 cup heavy cream
1/2 tablespoon sugar
1/4 teaspoon vanilla
Instructions
Brew coffee in 4 cups water in coffee maker or large French press pot.
Place chocolate pieces in a large shallow pan such as a 9- by 13-inch glass casserole dish. Pour in hot brewed coffee and add sugar. Stir until sugar is dissolved and chocolate is melted.
Place dish in the freezer. Scrape mixture with a fork every 30 to 45 minutes, loosening frozen bits from the sides and bottom with each stirring until the granita is completely crystallized and no longer moist (3 to 5 hours). Cover and store in the freezer until ready to serve. Just before serving, loosen and stir mixture with a fork. Chocolate will remain in slightly larger chunks.
Whip cream to soft peaks, then add sugar and vanilla and whip just until combined.
To serve, spoon granita into sherbet dishes or parfait glasses. Top each serving with 2 tablespoons whipped cream.
