utensil and equipment

  
 ballon whisk

   A whisk is a cooking utensil which can be used to blend ingredients smooth or to incorporate air into a mixture, in a process known as whisking or whipping. Most whisks consist of a long, narrow handle with a series of wire loops joined at the end. The wires are usually metal, but some are plastic for use with nonstick cookware. Whisks are also made from bamboo.
Whisks are commonly used to whip egg whites into a firm foam to make meringue, or to whip cream into whipped cream.
   Whisks have differently-shaped loops depending on their intended functions

 history
   Bundles of twigs, typically apple, have long been used as whisks; often the wood used would lend a certain fragrance to the dish. An 18th century Shaker recipe calls to “Cut a handful of peach twigs which are filled with sap at this season of the year. Clip the ends and bruise them and beat the cake batter with them. This will impart a delicate peach flavor to the cake.”
    The wire whisk was invented by the Victorians in the 19th century, however, they were not in common use until Julia Child used one in her first ever televised appearance, in 1963. The television broadcast was on the television show "I've been Reading" to promote her new book “Mastering the Art of French Cooking.

 blender

   A blender is a kitchen used to mix, purée, or emulsify food and other substances. A stationary blender consists of a blender jar with a rotating metal blade at the bottom, powered by an electric motor in the base. Some powerful models can also crush ice. The newer immersion blender configuration has a motor on top connected by a shaft to a rotating blade at the bottom, which can be used with any container

   Countertop blenders are designed to mix, purée, and chop food. Their strength is such that the ability to crush ice is an expected feature.
   Blenders are used both in home and commercial kitchens for various purposes, including to:

• Blend ice cream, milk, and sweet sauces to make milkshakes
• Mix and crush ice in cocktails
• Crush ice and other ingredients in non-alcoholic
• Make smooth purées of semi-solid ingredients, such as cooked vegetables and meat
• Reduce small solids such as spices and seeds to powder or nut butters
• Blend mixtures of powders, granules, and/or liquids thoroughly
• Help dissolve solids into liquids

   In 1949 the company Vitamix advertised their blender in one of the first television infomercials. The sales pitch lasted for 25 minutes, suggesting that the blender be used to make bread crumbs, potato pancakes, laxative spinach drinks, and a dessert beverage featuring entire raw eggs and their shells, which the host announced would be enjoyed like Malted milk
