A mortar and pestle, the pestle having a dome-shaped top formed to be cupped within the palm of the hand, a body, and a bottom portion, the bottom portion formed to include a male apex. The interior of the mortar is formed to include an inverted frustum-shaped wall and an interior bowl extending from the interior inverted frustum-shaped wall. The bowl includes a female apex which cooperates with the male apex and into which the male apex may nest. The pestle has an external surface profile which is substantially similar to, and cooperates with, a mortar internal surface profile. Rotating the top of the pestle in a smooth, continuous motion about a circular locus processes material placed in the mortar as the pestle profile sweeps the mortar profile. |
