Nancy Olson's Lemon Verbena Granita

I think this is a perfect recipe to make in the summer. It requires very little time in the kitchen, and it's deceiving—it looks so plain and simple, but the flavor of it absolutely pops. The granita needs no garnish, but it is a perfect accompaniment to perfectly ripe nectarines or raspberries. If you cannot find fresh lemon verbena, you could substitute fresh lemon balm or lemon thyme. (I would not suggest using dried lemon verbena. It doesn't have the same bright, fresh flavor.)
