Sugar and nothing but sugar

Cotton candy is the purest candy there is: it is quite literally just sugar, melted and spun into threads so fine they collapse the instant they touch your tongue. There is no chocolate, no fruit, no filling, only crystalline sugar transformed by heat and motion into an airy cloud. December 7 celebrates this fairground classic, a treat that is as much a piece of theater as it is a sweet.

A machine did the impossible

The magic of cotton candy is really the magic of a machine. Fittingly, the spinning-sugar device was co-invented by a dentist around the turn of the twentieth century, and it drew huge crowds at the 1904 World’s Fair under the name fairy floss. Inside, a heated central head melts sugar and flings it through tiny holes; the threads cool the moment they hit the air and are gathered onto a cone or into a bag. Watching that happen never really gets old, which is why the machine is as much the attraction as the candy.

Bring the fair home

You no longer need a carnival to enjoy it. Countertop cotton candy machines are inexpensive and genuinely fun, spinning ordinary floss sugar, or even a handful of unwrapped hard candies, into fresh clouds in seconds. It makes a fantastic centerpiece for a kids’ party, though a word of warning: fine sugar drifts everywhere, so set up over a table you do not mind wiping down, or work outdoors. The novelty of making your own more than makes up for the cleanup. A small handful of leftover hard candies works in a pinch, spun straight into floss, and older kids can run the machine themselves with a bit of supervision. It is the rare dessert that doubles as its own entertainment.

Cotton candy is the only candy that is mostly air, and somehow that is the whole appeal.

Flavors and clever tricks

Modern floss sugar has come a long way from the pink-and-blue default. You can buy it in vanilla, bubblegum, sour apple, watermelon, root beer, and dozens more, which turns a simple machine into a build-your-own bar where everyone picks a flavor. Cotton candy also makes a showstopping drink garnish: perch a tuft on the rim of a glass and pour in soda or lemonade, and it dissolves before your eyes, sweetening the drink as it melts. However you spin it, December 7 is a reminder that sometimes the simplest ingredient, handled cleverly, produces the most delight.
