I like both a handheld and an electric frother. I own the Nespresso frother, which is quite pricy but came with my machine when I bought one. I do love it and recommend it though, it can froth your milk both cold and hot! This is a cheaper version that does both hot and cold frothing. You can also make this recipe without a frother. You can use a whisk, a blender, an electric mixer, or even a mason jar with a lid.
