How to Make the Fondant Get Hard

Fondant naturally hardens when exposed to air over a period of several days. You can speed up the process by mixing the fondant with gum paste, which dries faster and harder than traditional fondant. Mixing the two ingredients will make the fondant inedible, but hardened fondant is hard to eat and usually does not taste good anyway. Hardened gum paste or fondant is recommended for decorative use only. If you want to eat the fondant, keep it in an airtight container to keep it soft.

Coat the rolling surface and your hands with shortening.

Roll two equal sized balls of fondant and gum paste. The amount you need will vary with how large of a project you want to make. For most larger projects, such as making a lot of flowers or building a large bow, you will need about 0.227kg of fondant and 0.227kg of gum paste.

Work the two balls together with your hands until they create one even mass. If you use two colours that are slightly different, then you will be able to tell when they are combined when you can no longer differentiate two separate colours.

Roll out the fondant and cut out the desired shapes, or form the fondant into the desired sculpture shape.

Place the sculpture or flat pieces onto a sheet of waxed paper. Place the waxed paper in a dry, out of the way area. Allow flat pieces to dry for 24 hours. Sculptures may take longer to dry, and you should allow three days for the sculptures to dry completely. After the fondant dries, you can store it in an airtight container. Do not store fondant in the refrigerator or freezer, as the sugars will break down and ruin the fondant.
