First I pour cream on the bottom of a glass and add some vanilla sugar to it. Second I take a tiny cup, and I fill it with snow. Then I measure the temperature of the snow. I pour a lot of salt there, I mix the snowy mixture, and I measure the temperature again. The temperature is falling. When the temperature is around minus 12 degrees Celsius, I put the glass with cream and sugar into it. Third I stir the cream to make it smooth till it´s frozen, and I taste it.
