With this milk frother, you can create a creamy milk foam with a firm consistency that doesn’t collapse immediately. This small frother doesn’t promise anything it can’t deliver: The sturdy spiral springs at the bottom of the rod form two concentric circles with a relatively large diameter—at least compared to the typical battery-powered plastic frother, which doesn’t inspire much confidence. The (hand-powered) back-and-forth motion creates a faster swirl, and the rotation speed can be finely adjusted—there’s virtually no risk of splashing.
