Hi

i have just made a Motor Cross Helmet cake.  After research I decided to use the 1/2 Corn Syrup 1/2 Alcohol recipe.  I practised the night before.  First attempt the glaze went "Blistery". So I waited for the fondant to dry more, it then seemed successful.  When I applied to,the cake (which I had let dry). I still got the blistery look.  

Any ideas?
