In British English, a BlenderCommand or a liquidizer is a kitchen appliance used to mix ingredients or puree food. It is an electrical appliance with a swirling blade for chopping, mixing, or liquefying foods. Most blender containers are tall and narrow, so air is not incorporated into the food, so this appliance will not "whips" foods such as egg whites and cream. They are ideally used for making soups, purees, sauces, milkshakes and other drinks and chopping small amounts of foods such as breadcrumbs, cheeses, nuts and herbs.

Dr Oliver Johnson Schofield, an English engineer and entrepreneur, invented the first smoothies blender. However, Stephen Poplawski, the Stevens Electric Company owner, was the first to patent the blender in 1922. He started to design drink mixers and patented them, designed to make Horlicks malted milkshakes at soda fountains. In 1946, Oster manufacturing, a manufacturer of barber equipment, bought out Stevens Electric and commercialized the blender under the name Osterizer.

Blenders are used both in-home and commercial kitchens for different purposes. It can be used to crush ice and other ingredients like non-alcoholic drinks such as Frappuccinos, blended ice coffee and fruit smoothies. It mixes and crushes ice in cocktails such as the Zombie, Pina Colada and frozen margaritas. It also makes smooth purees of semi-solid ingredients, such as cooked vegetables, meat, and even baby food. It cut down small solids such as spices and seeds to powder. It can even blend mixtures of powders, granules, and liquids thoroughly and smoothly. And it helps dissolve solids into liquids. It also chops nuts easily. In a matter of seconds, you will have finely crushed nuts.

Blenders are made of glass, plastic, stainless steel, or porcelain. There is a movable cover at the top of the container to prevent ingredients from leaking during the process. At the bottom centre is the metal blade that chops, grind, or blends food items. The container itself rests on top of a base that activates the metal blades when plugged into an electrical outlet. The bottom has different settings which control the edges, such as chop, blend, grind, pulse and liquefy.

There are a lot of blender in the market nowadays. Some could be cheaper, but some are a bit expensive. Plastic containers are less expensive, and they do not break easily; however, if you wash plastic containers in the dishwasher, they could scratch the machine. If you choose a glass container, they are more expensive and may break easily, but they are much less likely to score in the dishwasher. It is up to you which type of blender you should get. Choose the perfect blender that best suits all your blending needs.
