With the Mash&Store set, you can make fresh, homemade guacamole and other foods like hummus, baba ghanoush, and baby food, which can then be consumed or stored in the jar. The glass sliding lid is equipped with a silicone seal to keep the contents fresh. Simply place the blending basket on the jar, fill it with the desired recipe, and then press down with the immersion blender to achieve the desired consistency.
