I have been making the same recipe of fondant since starting to make cakes Jan 2011.
Within the last few months it has intermittently not been right. most of the time it has been perfect!
I thought it may be the weather but I dont recall thia happening last year at the same time.
I am using the same ingredients 7g gelatin powder with 1/4 cup water, heated in microwave, add 26g (2 tbsp) trex, 100g glucose, 5g glycerin optional 5g flavouring 2lb sifted icing sugar.
It does not come together, breaking and not holding. I will roll but you can tell it will not be good, as soon as you start to lift it it tears.
I have tried puting in microwave to warm through - this does not work
I have tried adding more trex - this does not work
Any ideas please. I binned two batches last week, another 2 have failed last night and this morning and I refuse to bin them (approx £4 ingredients) - Thank you for any replies in advance
