Meant for smaller and tougher blends, the Twister Jar is ideal for recipes that call for more stubborn ingredients, such as acai breakfast bowls, thick milkshakes, nut butter, hummus - even bread & cookie crumbs. To use the jar, simply add ingredients and twist the lid counter-clockwise while the blend cycle is running. This twisting motion forces the ingredients from the sides of the jar back into the blade, allowing you to achieve amazing blends every time.
