In a high powered blender, pulse to coarsely chop.
Add ¼ cup of hot water to blender and allow dates to rehydrate for 5 minutes.
Puree 10 minutes until smooth stopping occasionally to scrape down sides. Add 1 Tbsp more water at a time to reach desired thickness. (Thick like the picture is ¼ cup. Your blender will get very HOT. See notes)
Notes
This is the ultimate natural sweetener. Dates are extremely sticky and will cause your blender to work overtime. I do not suggest trying this recipe without a heavy duty blender like a Ninja or Blendtec. Chances are it will burn out the motor of a regular blender and food processor. You have been warned from someone who has burned through 2 food processors and regular blender! :P
