Wash the berries.
Place the berries in a medium saucepan, along with the ½ cup of water.
Simmer, stirring frequetly, until the berries have mostly broken down and formed a thick sauce. This could take 20-30 minutes depending on your berries.
Taste the sauce to see how much, if any, sweetener you need to add.
Serve warm, or allow to cool before using.
