Switch the heat on for boiling the milk and when it is lukewarm, take aside a cup of milk. Allow the rest to boil & meanwhile add custard powder to the cup of lukewarm milk & ensure it is lumps free. Now add sugar to the boiled milk and let it dissolve. Pour the custard mix into the boiling milk while stirring it continuously. This is to ensure lumps are not formed. Now the milk immediately starts to thicken, let it cook for a minute and switch the heat off.
While it cools down, take a fruit of each variety listed and cut them into small pieces. Also split the cashews & slice the almonds vertically. One can actually add/remove the fruits per their liking except banana. Now, when the milk is still lukewarm, add bananas and allow it to cool down completely. Add rest of the fruits & dry fruits and mix them well. Refrigerate it & serve chilled!!
