Apparatus for providing a frothed mixture of milk, air and steam has a mild reservoir, and a steam boiler. A pump draws milk from the milk reservoir and delivers it to an inlet of a Y-connector forming a mixing chamber. A second inlet of the Y-connector is fed with steam. The pump and the steam pressure are controlled such that the milk and steam are substantially of an equal pressure. The milk-steam mix is fed to a jet and exits from its outlet nozzle. The milk-steam mix expands as it exits from the nozzle. Furthermore, the flow of the milk-steam mix draws air into the mix by way of an air inlet conduit whereby a frothed product of milk, air and steam is produced at the nozzle.
