Liquid nitrogen ice cream

Store the liquid nitrogen in a vacuum-insulated dewar, in a clean container, using a high purity grade; work in a ventilated space.

Pour the ice cream base into the mixing bowl and start mixing fast to work in air bubbles.

Slowly pour in liquid nitrogen while mixing, adding small amounts until the ice cream reaches the desired consistency.

Pour while wearing a face shield, apron, long sleeves and a loose-fitting insulated glove.

Make sure all the nitrogen has evaporated and the ice cream is no longer extremely cold before serving.
