This natural fruit acid is commonly added to hard candy and creams to enhance the taste of fruit flavors. It is recommended to use 1/8 teaspoon per 2 cups of sugar and should be added once the hot syrup cools below 265º F. Citric acid can also be combined with granulated sugar to create a sweet and sour coating for finished hard candies and lollipops, with the amount adjusted for desired tartness.

Besides its culinary uses, citric acid is also an ingredient in bath fizzies (bath bombs) to create a fizzing effect. It is kosher certified and gluten-free, making it suitable for various dietary needs and applications beyond candy making.
