I made a beautiful fondant number 5. It broke with a clean break. How can I fix it? I only have about 2 hours until delivery. Thank you in advance.

AIs it bone dry.to the core? if not, take a toothpick and break it small enough to insert into the broken part, make some tylose glue to hold the pieces together with the toothpick, and stick the other end down over the toothpick.

AMelt some candy melts and "glue" it back together. If you had more time, I would recommend royal icing - but chocolate will work as well.

Take a small flat piece of fondant mixed with tylose, for strength, in it and glue it to the back of the 5 with tylose mixed with water as a gel glue.

Or use the tylose glue and glue a skewer or toothpick to the back and you can cover that with a fondant band-aid.    It works!
