CHEAPEST WAY TO GET IT - MAKE IT !
Others make it from scratch , but my attempts to make it that way did not yield comparable results to ready made gumpaste
The most economical way to make it is to add TYLOSE powder or CMC to fondant. The general ratio is 1 tsp to a pound but this will vary-- if i need it to dry faster I just add more.
GUMPASTE ISSUES:
Drying - always keep gumpaste wrapped in cling wrap and stored in a moisture free container; if the gumpaste feels hard, the last resort is to try microwaving it for a few seconds. about 5 seconds at a time. Dont overdo it or it will melt/burn. try rubbing shortening on it before you microwave it.
Cracks on gumpaste - while working with gumpaste, if you feel that there are some drying cracks on it, it needs shortening. knead on shortening for a few seconds and the consistency will change considerably!
Taste- gumpaste , for me, should not be eaten. It is considered EDIBLE but will have dried so much by the time it is served and would not really taste good. The role of gumpaste for me is to add art to an ordinary thing as cake... so use this tool as another way to spruce up your usual cake.
