It helps you to achieve perfect tasting and smooth results, whether you’re making nutritious homemade soups, baby foods, nut butters, sauces, dips or breakfast smoothies. The blender jar has internal ribs and corners to force ingredients back in towards the blade and help to create a powerful vortex inside. It comes with a secure lid and easy-pour spout.
