Take dates in a bowl and deseed them. Discard the seeds.

Add hot or warm water to the pitted dates till it immersed level. Soak the dates in water for 5 to 10 mins. Alternatively, you can also soak the dates overnight in water.

When the dates are soft enough to mash/grind, transfer to a blender along with soaked water. Grind it to a smooth paste. Don't add all the soaked water at once. Add little by little. The date paste should be smooth and thick.
