1. Begin by soaking the pitted dates in warm water for about 10 minutes to soften them. This will make them easier to puree.
2. After the dates are softened, drain them and place them in a blender or food processor.
3. Add the coconut flour and the remaining 150 ml of water to the blender with the dates.
4. Blend the mixture until it reaches a smooth puree consistency. You may need to add a little more water if the mixture is too thick for your preference.
5. Once blended, taste the puree to ensure the consistency is suitable for your baby. If needed, adjust with a bit more water.
6. Pour the puree into a clean container or ice cube tray for storage.
7. Allow the puree to cool before serving it to your baby.
