Made of stainless steel with a silicone coating. Fill the milk frother with cold milk (1% or 2% fat). The electric milk frother transforms milk into approximately 70°C warm milk foam in about a minute, whether for a latte macchiato or cappuccino. The milk frother can also be used to heat milk. It has 3 program levels: cold, chocolate, hot. Simply detach the whisk from the drive shaft.
