I followed this recipe to make gum paste:
3 CUPS icing (i used 360g)
2 tsp GUM-TEX
1/4 CUPS water (i used 60ML)
2 tbsp corn syrup
For knead after 8hrs
1 CUP icing (i used 120g)
1/3 CUP starch (i used 40g)
I rolled the gum paste too thin, to text the gum paste is it work.
However, the gum paste become dry and look like set already,
I touch it, the gum paste shattered.
