A blender includes a container having a plurality of substantially triangular shaped ribs projecting into a processing zone of the container. The plurality of spaced ribs each include a width and a depth that taper from a top end section adjacent a teardrop shaped opening of the container to a more narrow bottom end section adjacent a bottom wall of the container. A side wall of the container continuously tapers from the teardrop shaped opening to a substantially square shaped bottom end portion including first, second, third and fourth side wall sections connected to one another at respective rounded corners. A blade assembly is coupled to the container and includes a plurality of blades angled at different planes with respect to a horizontal plane. Each of the blades includes a beveled leading edge, resulting in a downward suction force that draws ingredients down into the blade for processing.
