Bring milk to boil in a heavy bottom pot. Keep stirring it frequently to avoid burning of milk at the bottom of the pot.

Mix 3 tbsp (use 2 tbsp for a little thin consistency) of custard powder with ¼ cup of milk to make a smooth paste.

Once milk comes to boil, bring the heat down, slowly pour the smooth custard mix (stir it well before adding) in the milk while mixing constantly.

Add sugar and mix well, let it boil for 10-12 minutes while stirring frequently.

Turn the heat off and let it cool down completely. You will see a layer of malai (milk fats) on top, you can either mix it well in the milk or discard.

Once cooled down, add jelly crystals on top and enjoy once chilled.
