Place the unthawed blueberries, honey, and the water in a pot. Turn the heat on medium high.  With the back of a wooden spoon, break up the blueberries until they are warm and start to burst open.

Once the berries have warmed up and burst open,  transfer it all to a blender, and blend and blend and blend.

Return the mixture to the pot and continue to heat it while stirring until it's thoroughly warm and the mixture begins to reduce and thicken.
