What ingredients make candy sweet?

The main ingredient that makes candy sweet is sugar.

Here's why:

* Sugars are naturally sweet: Sugars like sucrose (table sugar), glucose (corn sugar), fructose (fruit sugar), and lactose (milk sugar) are naturally sweet and provide the primary sweetness in most candies.

* Other sweeteners can be used: Some candies use alternative sweeteners like honey, agave nectar, maple syrup, or artificial sweeteners like aspartame or sucralose to reduce sugar content or cater to dietary needs.

It's important to note that not all candies are equally sweet. The amount of sugar used and the presence of other ingredients like acids, salt, or fats can affect the overall sweetness perception.
