With this new, sensational milk frother, the perfect foam comes at the push of a button. An absolute novelty, the Bodum Latte"s foaming spiral not only rotates in both directions, but it also moves up and down, thus pumping more air into the milk and making the foam, to put it simply, even foamier. The Bodum Latte houses batteries in its rubber lid and a big button on top to get it going. It"s designed for 0.2 l milk to be foamed at a time. For best results use ice cold non-fat or low-fat milk, froth it and then put the Latte into the microwave for hot foam. The Latte frother is also great for other light mixing such as protein drinks, sauces, salad dressings and more. The large glass beaker is heat resistant and can be used with hot or cold liquids. Requires 4-AA batteries - not included.
