A food processor and a blender look very similar. However, their functions are different. It is impossible for a food processing machine to perform the same functions as a blender. Blenders usually have one blade which can whip or puree ingredients to make liquid or paste. You can make smoothies. Nut butters, soups and sauces are all great examples. Food processors usually have multiple blades that can be used for various tasks. The majority of food processors will be able to cut, chop and mince. For coleslaw, you can use a food processor to cut and grate the cheese.
