Bring berries and water to a simmer in a small pan. When then begin to soften add honey and vanilla. Start with 1 tablespoon of honey and add more depending on the amount of sweetness you like. Cook until fruit is very soft. Let cool slight then, using a blender, blend until pureed. If you don't want seeds then pour sauce through a mesh strainer. This will be messy.
Serve over yogurt or any way you use a sauce.
Store in container in the fridge for about 5 days. It can also be frozen using freezer bags or containers.
