Ruby Grapefruit Granita

Directions

1. 1
   Place a 9-inch square baking pan in the freezer. Grate peel from 1 of the grapefruit. Segment both grapefruit; set aside.
2. 2
   Place 2 cups water, sugar, grapefruit peel and cinnamon sticks in a medium saucepan on high heat. Bring to a boil, stirring, until the sugar dissolves. Reduce the heat to low and simmer for 3 mins, without stirring. Remove from heat and stir in the grapefruit juice. Cool to room temperature. Remove the cinnamon sticks.
3. 3
   Pour the grapefruit mixture into chilled pan. Freeze for 3 hours, removing every 30 mins to break up the ice crystals with a fork. When set the granita should have the texture of soft, crushed ice. Scoop into serving cups and top with the grapefruit segments.
