Raspberry sparkling wine has a pretty pink color and lightly sweet flavor; you can use regular sparkling wine for a less sweet dessert. Or you can skip the alcohol and use raspberry-flavored seltzer water instead.
Scoop 1/2 cup sorbet into each of 4 wineglasses or small bowls, and drizzle each serving with 1/4 cup wine. Top each serving with 1 1/2 teaspoons chocolate. Serve immediately.
