Blendtec Frothing Jar, the wave of the future! High capacity frothing is finally here! Combining the volume of the traditional FourSide jar with an innovative, stainless steel frothing blade results in a quick, effective way to froth or aerate liquids. 2 Quart capacity provides a huge capacity for producing frothed liquids and foam. Instead of repeatedly creating single servings, you can now produce in batches and serve several customers at once. The stainless steel blade features a “wave” bend which enhances the frothing capability —easily doubling the volume of many liquids. The blade works great for cold foam, whipping cream, hot chocolate, syrup and more! 3 year warranty.
