A smoothie (alternatively spelled smoothee or smoothy) is a blended and sometimes sweetened beverage made from fresh fruit, vegetables and, in special cases, chocolate or peanut butter. In addition to fruit, many smoothies include crushed ice, frozen fruit, honey or contain syrup and ice ingredients. They have a milkshake-like consistency that is thicker than slush drinks. They can also contain milk, yogurt, low fat or cottage cheese, ice cream, lemon water or tea. Smoothies are often marketed to health-conscious people, and some restaurants offer add-ins such as soy milk, whey powder, green tea, herbal supplements, or nutritional supplement mixes.
The electric blender gave birth to the smoothie in the United States. Smoothies became widely available in the United States in the late 1960s when ice cream vendors and health food stores began selling them. By the 1990s and 2000s, smoothies became available at mainstream cafés and coffee shops and in bottled versions at supermarkets all over the world.
Health food stores on the West Coast of the United States began selling puréed fruit drinks in the 1930s, based on recipes that originated in Brazil. The 1940s-era Waring Blendor cookbooks published recipes for a "banana smoothie" and a "pineapple smoothee." The first trademark for a fruit slush was in the mid-1970s with the name "California Smoothie", which was marketed by the California Smoothie Company from Paramus, New Jersey. Smoothies from the 1960s and early 1970s were "basically fruit, fruit juice, and ice"; in some cases in the early 1970s, ice milk was also blended in to create the "fruit shake". These shakes were served at local health-food restaurants and at health-food stores alongside tofu, fruits, carob, and other health-oriented foods.
Since the 1990s, many smoothie companies have been using frozen yogurt to give their smoothies a thick, creamy, milkshake-like texture. Many types of fruit smoothies are found in Mediterranean, Middle Eastern and Indian cuisine, including sharbat, which is typically made of yogurt and honey, as well as a range of fresh fruit. In India, the traditional mango lassi is really a summer smoothie in which tota puri mango, crushed water ice, milk and cane sugar are mixed into a thick smoothie using a blender, while in South India, pineapple smoothies with crushed ice and sugar (without milk) are more popular. Smoothies can also be mixed with soft drinks and/or alcohol to make cocktails.
