A food processor includes at least two different types of blades to process foods. A processing assembly includes a shaft, a set of pureeing blades attached to the shaft, and a set of substantially horizontal blades attached to the shaft. Each substantially horizontal blade may have a rearwardly curved leading cutting edge. The substantially horizontal blades are positioned higher with a food processing container than the pureeing blades. In some embodiments, upwardly angled blades may be included to induce vertical circulation and/or vorticial flow of the processed food.
