Ice cream
Ice cream is a frozen dessert commonly made from milk, cream, sugar and flavourings. Churning incorporates air while the mixture freezes. The texture depends on the ingredients, the air bubbles and the size of the ice crystals, rather than on freezing alone.[1] It is served in bowls or edible cones, while related desserts such as kulfi are frozen in moulds.[2]
Composition and preparation
Ice cream combines dispersed fat droplets, ice, air and a liquid containing dissolved sugars. Its air content affects its density. The increase in volume caused by adding air is called overrun: doubling the original mixture's volume gives an overrun of 100%. Dissolved sugar lowers the mixture's freezing point. Emulsifiers help control the way fat droplets gather and retain air; lecithin from egg yolks is one example.[3]
An ice cream maker mixes and cools the ingredients together. Rapid freezing helps limit crystal growth; larger crystals give a coarser, icier texture. The mixture's viscosity also affects the result. Stabilisers can increase viscosity, while changes to the proportions of fat and sugar alter the mixture's physical behaviour. Plant-based versions can replace dairy ingredients with coconut, soya or almond milk, requiring adjustments to the formulation because their fat content differs.[1]
Forms and related desserts
Soft serve is dispensed at a warmer temperature than firmer ice cream, contributing to its softer consistency. Frozen custard contains egg yolks and is churned to incorporate less air, giving a denser texture. Frozen yoghurt uses yoghurt as its principal dairy ingredient.[3]
Kulfi is a distinct South Asian frozen milk dessert. Its milk is slowly reduced by cooking, flavoured, poured into moulds and frozen. It is not churned in the same way as ice cream. Traditional flavourings include cardamom, saffron, pistachio and rose. Its history is associated with the kitchens of the Mughal courts in the sixteenth century, although its precise origins remain uncertain.[2]
Historical development
Accounts that credit Marco Polo with bringing ice cream to Europe, or Catherine de' Medici with introducing it to France, are disputed. Earlier iced drinks and milk-based frozen confections differed from modern ice cream. Seventeenth-century European recipe writing records a range of frozen desserts: Antonio Latini described a milk-based sorbet, while French confectioner Nicolas Audiger discussed fruit ices and a preparation using cream, sugar and orange-flower water. Audiger also described stirring during freezing to incorporate air. Moulds allowed cooks to shape frozen desserts, including forms resembling fruit and animals.[4]
Street vendors used reusable glasses known as penny licks before edible containers became widespread. Ice cream cones were sold at the 1904 St Louis World's Fair, but accounts attributing their invention to a single improvised waffle are poorly supported. Edible cups and other precursors already existed.[5]
Motorised vending expanded another route to customers. In the United States during the 1920s, confectioner Harry Burt developed a business selling chocolate-covered ice cream on sticks from refrigerated trucks. By the end of that decade, the vehicles carried freezer units; bells announced their arrival. Later vans allowed vendors to serve customers through a side window. These changes made mobile refrigeration part of the street sale of frozen desserts.[6]
