Quantities vary according to the food being processed and the task you are performing. The bowl holds more when slicing or shredding foods than when chopping or mincing.
Food processors are classified according to their dry ingredient capacity, ranging from 3 to 20 cups. As a general guideline, the liquid capacity is about half the dry ingredient capacity. Follow the guidelines in your manual for recommended capacities.
When chopping and puréeing fruits or vegetables, don’t fill the bowl more than one-third to one-half full. For larger quantities, process food in batches.
