Sago Soup

1 full package Minute tapioca
1 full box raisins
1 full box currants
3 teaspoons cinnamon
2 to 3 1/2 cups granulated sugar
2 lemons, sliced very thin
3 quarts water
2 quarts frozen blackberries

Boil water, then add tapioca. Cook and keep stirring so it doesn't stick or get lumpy. Add at least 2 cups of the sugar and the cinnamon. Stir and then add raisins and currants. Add blackberries. Continue cooking, tasting and adding more sugar until it is to the desired sweetness.

If you can't find blackberries, you can use grapes, and add food coloring for a deep purple color.
