You will need whipped cream, choco-cornflakes, Granko, cocoa Pikao, sugar, a solid plastic bag, gloves, a tea towel and liquid nitrogen. Cream, in this case, represents water ice; other ingredients represent impurities of different sizes. We pour everything into the plastic bag that is held by a helper wearing gloves. We gradually pour the liquid nitrogen in the bag, while kneading everything from below with the use of the towel. When the mass begins to solidify, we shape a lump, put it on the plate and we can serve. About one litre of liquid nitrogen is needed per a cup of cream.
