Q&A: How to keep sugar figures dry in humid season?

The only thing I can suggest is to add a bit more Tylose or powdered sugar to make the model stronger and try and keep it in the coolest part of the house.

Firstly I use a combination of modelling chocolate and fondant + tylose for my figures. More workability and dries lovely and hard. Keep the figures in a box in the coolest room in your house. And I also use silica gel packets to keep inside the box. The silica gel absorbs dampness and humidity. Posted a picture as example.
