I have a 250g block of black Regalice from Redshaws. I want to flavor the icing with a concentrated peppermint flavoring. Only a very small amount to achieve a subtle hint of mint, the icing is just to lay over the cake.. Will the icing become to moist/tacky if I add any kind of liquid? I plan to use edible silver paint to add some details when it is finished.
If it does become too moist, what can I do to help it become dry?
I do not want to mess up and I am on a deadline so please help me :)
