50 g/2 oz dried blueberries or dried rose hip berries
3/4 cup sugar
2 tbsp potato starch
Cover washed in hot water dried blueberry (or dried rose hip berries) with 2 cups of water, bring to boil, and cook 15-20 minutes. When blueberry becomes soft, strain the cooking liquid into a different pot, mash berries with a pestle or a spoon, add 1 cup of cold water, bring to boil, and strain again into the pot with cooking liquid, pressing on solids to extract as much liquid as possible. Add sugar to strained cooking liquid, bring to boil and add potato starch dissolved in water.
