Abstract: This invention relates to an ice cream making machine which comprises a motor unit operative to rotatively drive a cold storage container whereinto the the mixture to be whisked is introduced. The container includes an inner metal vessel around which an outer case is provided to define a space therebetween. A eutectic liquid is introduced into said space which, when brought to freezing temperature, is effective to keep the vessel at a nearly constant temperature which ensures whisking of the ice cream mixture. The container outer case has a bottom which is expandable relatively to the inner vessel to accommodate expansion taking place during the change of state of the eutectic liquid.
