Mix together custard powder and enough water to form a loose batter.
Mix the rest of the ingredients in a pot and bring to boil.
Once boil, slowly thickened the base with the premixed custard mix.
Remove from stove once a thick custard is achieved. Temperate in room temperature or on an ice bath until the custard is cooled to room temperature.
Pour the ice cream into a large bowl. Crush some dry ice with a pestle and mortar and slowly introduce the shards into the custard mix. Mix continuously until the dry ice is all dissolved.
Gradually add more dry ice shards and continue whisking until an ice cream consistency is achieved.
Keep in the freezer overnight. Ready to be served.
