In a large bowl, combine all the ingredients. Using a hand blender, you can mix all the ingredients in just a minute. Make sure that you whisk away any clumps of milk powder left in the mix. Alternatively, you can use a blender as well.
Cover and keep it in the fridge till the time you are ready to churn. Please note that it is quite important for the ice cream base to be really cold.
Wear your gloves and carefully shift the dry ice to a clean tea towel or apron. Ensure that you wrap it up completely. Don’t forget to wear gloves as the dry ice will be extremely cold.
Using a hammer or a heavy cast iron pan, crush the dry ice until it becomes a fine powder.
Now shift the crushed dry ice to a plastic bowl or Tupperware container. Keep it inside the freezer till you are ready for it.
Transfer the ice cream base into the bowl of a stand mixer fitted with the paddle attachment. Start mixing at medium speed.
Now add one spoonful of dry ice at a time. Let the foam and steam dissipate, then add one more spoonful. It takes close to 5 minutes.
NOTE - Don’t make the mistake of adding a large quantity too quickly as it will lead to a big pile of bubbling ice cream all around.
Continue adding spoonfuls of dry ice until the ice cream turns out to be thick. Once it is thick, increase the mixing speed and keep adding spoonfuls of dry ice until your ice cream becomes rich, thick, and creamy.
Store in the freezer until you are all set to serve. Mix up the ice cream once more and scoop it into a piping bag attached to a big, round nozzle.
Pipe into your cones and eat the yummy soft serve straight away. Freezing overnight is not recommended as it becomes hard to scoop later.
