The colder your ingredients are the less liquid nitrogen you will end up using.

Mix up ingredients, then, working in a well-ventilated area gently fold the liquid nitrogen into the base a small amount at a time. Wearing appropriate cloves is a good idea, oven mitts should not be used.

Keep stirring continuously such that you parts of the base don't freeze solid.

Keep adding liquid nitrogen until the base has reached the right consistency and serve once you are certain all the liquid nitrogen has left the base.
