sweating fondant

please what shld i do,my fondant and gumpaste flowers are sweating,we presently in d wet   season in my country  ,but i dont ave dis problem during the dry season


I live in Australia and during summer the fondant can sweat. The reason that fondant sweats is because sugar attracts moisture from the air, therefore the more moisture that is about, the more it affects the sugar which makes it 'sweat' and become soft.

My solution to this is to:

  1. Decorate at night when the humdity drops then
  2. Keep the cake in a cupboard with one of those humidity absorbers (closet hippo, damp rid etc) or a large box with a lid, that has layer of the crystal type kitty litter on the bottom. You then put a couple of layers of kitchen paper over the top of this so none of it is touching the cake or decorations. It acts just like silica gel and is inert and non toxic, and cheaper.
  3. Crank up the air conditioning - but once the air con is off the cake will sweat again unless you have placed it into 2.
  4.  Keep a fan blowing across your work area to keep the air moving and drying out the icing as you work then (see 2)
  5. Adding tylose powder to your decorations will also help make them more resistant to the effects of humidity
  6. Dipping your decorations into confectioners glaze will also provide a physical barrier between your decoration and the humidity, BUT it will make everything look shiny and plastic.

Perhaps store with in a box with food grade silica gel in future?



Reduce the glucose you use for your fondant mixture and add a little bit more of cmc.


When glucose is much, fondants sweat


A bit more of CMC helps to harden the fondant, prevent it from sweating.
