Granny Smith Apple Ice


1¼ lbs Granny Smith Apples (or your favorite tart apple)
the juice of one medium lemon
2/3 cup agave (or honey)
½ cup water
1 2-inch piece of cinnamon
1 tablespoon fresh ginger, grated

Core the apples and keep the skin on, but quarter them, then cut into thin slices. Toss with lemon juice and let them sit overnight. The next day, make a simple syrup by adding the agave and water in a small saucepan and bringing to a boil. Add the cinnamon and ginger. Simmer for 5 minutes, then pour over the apples and stir. Puree in a blender or food processor until smooth, then freeze in an ice cream maker (according to manufacturer's instructions). The apple ice will be smooth and creamy--and delicious.
