A food processor is a versatile kitchen appliance that aims to do most jobs you could want to do in a kitchen when preparing food, both more quickly and with less effort than it would be to do such jobs by hand. The primary functions of a food processor are chopping, slicing and shredding. Typically they also come as standard with an egg/cream whisk, dough making tool, juicer and liquidiser.
A blender is a device almost entirely for the purpose of turning foodstuffs to liquid or puree. It is used mainly to make soups, pates/baby food and blended drinks, but can also be used to crush ice. Some are supplied with a mill to grind coffee beans, herbs and spices.
