Stir and all the sugar dissolves in the hot version while myriad undissolved crystals remain at the bottom of the iced tea. That’s because the amount of sugar that can dissolve in water depends on the temperature— higher temperature, more sugar dissolves. Many materials are soluble in water and sucrose is one of the more soluble ones. At room temperature, a saturated solution, one that has as much sucrose dissolved as it can possibly hold, is two-thirds sucrose and one third water.

In fact, cream of tartar is still added to some confections to provide control of sucrose crystallization. It works by causing the hydrolysis of sucrose, a disaccharide, into its component monosaccharides, glucose and fructose. The acidity from adding cream of tartar, along with the elevated temperatures usually found in candy processing, leads to hydrolysis of the sucrose. Hydrolysis of sucrose due to addition of cream of tartar creates a doctor, called invert sugar. The glucose and fructose molecules of invert sugar interfere with the ability of the sucrose molecules to come together and crystallize.

If the results of a recent informal internet survey have any validity, we’re split on how we prefer to eat hard candy—there are about as many people who suck their hard candy as there are those who crunch it. But, that depends a little on which hard candy we’re eating. LifeSavers, made with more sugar than corn syrup, are hard and crunch nicely in the mouth.
