Tylose Powder is a hardening agent which when added to fondant creates a quick and simple version of gum paste/modelling paste.
The most common question we are asked about using Tylose Powder is
“How much should you use in the fondant”?
Unfortunately there is no real exact guide as there are different factors that influence the end result such as humidity. In areas with high humidity you will need to use more Tylose than in places with low humidity.
The best way to gauge how much to use is by kneading a little at a time into the ball of fondant you are using.
For example; Try taking a small ball of fondant the size of a golf ball and knead in approximately 1/2 teaspoon of Tylose powder. You will start to feel the fondant consistency change and start to feel firmer.
You will know if you have added too much Tylose as the fondant will be too hard to knead and work with (in my case, the fondant will start cracking). In this case you can add some more fondant to the mix.
Only mix the Tylose Powder into the fondant when you are going to use. If you mix the fondant too far ahead of time it will set before you are ready to use it.
When you have made your decorations leave them overnight to completely set/dry.
