If dates are seedless then can be used directly or else de-seed the dates and keep.

Boil milk with water. Once boiling add the seedless khajoor and lower the flame.

After 8 to 10 mins. Switch off te flame and leave the mixture to cool. Check if the dates are soft.

Once the milk had cooled down transfer it to a mixie jar. To it add cardomom or vanilla essence, sugar (as per your taste).

It's ready! Serve it in a glass. It'll taste better if served cold.
