Place dates in a bowl and cover with hot water. Let soak for at least 30 minutes until soft and mushy. Save the water!
Add pitted dates to a powerful blender and blend, slowly adding in the water you soaked them in. Continue adding water until you achieve desired consistency (I use about 1 cup).
Notes
The longer the dates are soaked, the smoother the consistency.
You have full control over the desired consistency. The thicker you want the date syrup, the less water you should add, and vice versa.
Store in an airtight container and refrigerate for 2-3 weeks. Can also freeze for up to 3 months.
