Combine dried peaches and water and soak overnight in refrigerator to rehydrate.
In a large heavy pot, pour sugar and cook over medium heat, moving pan frequently but not stirring until the sugar melts and takes on a light amber hue. Off heat, careful to avoid any steam or sputtering, add one cup of the soaking water from the peaches. Stir over medium heat until the caramel has dissolved. Add the remaining soaking water, peaches, cinnamon stick and lemon (or orange) peel. Return to a simmer and cook until tender, about 30 minutes. Cool to room temperature then chill until cold. Add 2 to 3 tablespoons of cooked barley or wheat berries to the bottom of a tall glass.
Add 2 to 3 peach halves and top off with juice. Stir in additional sugar or honey to taste. Serve with a spoon to break up the peaches and scoop out the grains.
Note: Chile and mote can be difficult to find in the United States but cooked barley or wheat berries can be substituted.
