The basics of blending and processing food can be found in this infographic. It first explains the difference between the two appliances and goes into the qualities to look for when making it as a purchase. A blender is ideal for mixing liquids and a food processor is used for more labor-intensive tasks like chopping, slicing, shredding, mixing, and pureeing. Some of the qualities to look for in a blender are for it to be at least 500 watts with a stainless steel blade that is large enough for your needs. A food processor should be dishwasher safe and have a pulse button for quick processing. An average price for a blender can range from $30-$500 and food processors can be anywhere from $50-$400. These are both essential appliances to have in your kitchen especially considering that the food processor saves about 15 minutes each time you need to chop something.
