Briefly Cook the Berries
8 minAdd the red currants, blackberries, sugar, and water to a wide pot. Cook over medium heat for 3 minutes, until the sugar dissolves and the berries begin to release their juices. Remove from the heat and add the raspberries and quartered strawberries; let the residual heat soften them without breaking them down. Lift the fruit out with a slotted spoon and collect the juice in a separate bowl.
