Soak dates in water overnight.
Separate the dates from water, and place dates in blender or food processor.
Blend on medium speed adding date water as necessary to form a thick paste. You shouldn't need more than ½ cup of the date water, and even less for a thicker paste.
Store in fridge or freezer. Dates can be substituted with other dried fruits, however you may need to boil tougher dried fruits such as apricots and figs for 30 minutes before blending.
