A liquidiser is a kitchen appliance used to blend food to a smooth liquid consistency. Other synonyms for this device include blender, mixer, food processor, and puree machine. These machines are an essential tool in any kitchen, especially for making smoothies, soups, sauces, and baby food. While most people refer to this appliance as a liquidiser or blender, others may use terms like hand-held immersion blender or stick blender for a more portable option. There are also more specialized machines like the Nutribullet or Vitamix that can handle tougher ingredients like nuts and seeds, making them perfect for making nut butter or smoothie bowls.
