As i Live in Iran ,premade gumpaste is very expensive and hard to find here. I found an amazing recipe which i don't remember where did i exactly find it!
So I'm sharing it with you and i'm sure it would be very helpful for all of you specially for people who live in middle east cause it contains tragacanth.
1 pound 10x confectioners sugar
1 tablespoon and 1/2 teaspoon gum tragacanth
1 1/2 teaspoon unflavored gelatin powder
1 tablespoon shortening
3 tablespoon glucose
combine sugar and gum tragacant in a large mixer bowl.
soften gelatin in the cold water in a heatproof glass container.
allow this to stand for 5-15 minutes.melt shortening and cool a bit.to dissolve gelatin ,place glass container with gelatin water mixture in hot water and stir it to dissolve or just put it in microwave with highest power for 40-50 seconds(be careful not to overheat).
attach mixer bowl to mixer platform.add liquid mixture.mix to combine.at first the mixture will be very soft,beat on medium speed about 5 minutes.the mixture will stiffen up.a plastic scraper helps remove the sticky ,gooey mixture .the mixture will look like a big marshmallow.if you have used the full amount of water the mixture will be soft and likewise the mixture will be firmer with the minimum water added( i add the full amount of water).place in a greased airtight covered refrigerator container.
let it rest overnight.
