Most candies will keep well for two to three weeks if stored tightly covered in a cool, dry place.
It's best to avoid storing different types of candy in the same container because hard candies will become soft and sticky, and soft candies will dry out. Candies can also trade flavors while in the same container. In other words, don't store your Crystal Candies with Southern Pralines.
Protect sticky caramels, nougats, and popcorn balls from dampness by wrapping them individually in clear plastic wrap or waxed paper.
To store brittles, toffees, and homemade marshmallows, layer them in an airtight container between sheets of waxed paper. Homemade marshmallows need to be stored in the refrigerator.
Truffles should be stored in the refrigerator in a single layer in an airtight container. To preserve the glossy finish on chocolate-covered candies, separate chocolates from one another by storing them in paper candy cups. Place in a single layer in an airtight container.
To prevent divinity from quickly drying out, store it in an airtight container lined with waxed paper.
Gumdrops are an exception to storing candies tightly covered. They need to be loosely covered so their surface remains dry. Moisture makes the sugar coating soft and sticky.
For longer storage, candy can be frozen. This is especially convenient when planning for the holidays.
Fudges, pralines, and caramels freeze well. Even chocolate-covered candies freeze successfully.
To freeze pan-shape candies (such as fudge), remove candy from pan; place in an airtight freezer bag or container.
Chocolate-covered candy that is boxed and ready for a gift can be frozen. Just wrap the box in moisture- and vaporproof wrap or place in an airtight freezer bag.
To freeze popcorn balls, first wrap the balls individually in clear plastic wrap, then place them in an airtight freezer bag.
When removing candy from the freezer, let it stand several hours to warm to room temperature before opening or removing the wrapping. This will prevent moisture from collecting on the surface of the candy and causing white speckles or gray streaks.
