i appreciate your reply but your wrong about the coloring. Ive successfully used gel colors to color chocolate for cookies and other covered treats. i had just never done chocolate like this. I have already completed 3 of the 4 sets of birds and they are just fine. i never add ALOT of gel color and, for example the red i needed, i started with half white and half milk chocolate. it was dark enough where i only needed a lil bit of color. it set up perfectly well and looks awesome.
i didnt need to reverse the image as i let my chocolate cool a little, and then proceeded to pipe it out as i would have done royal icing. i used a pipe by numbers kind of technique and the chocolates all joined together just right. the front looks about the same as the back minus lil details i added when it was all dried.
and the curling thing... has never happened when ive piped out chocolate.. i put my antlers in the freezer right after i piped them and they never curled. i put these angry birds in the freezer to set the colors in between other color additions and nothing ever curled. perhaps because they are not wafer thin... but then again, even my antlers were wafer thin...
either way im almost done with the birds... they look awesome and i didnt deviate from my plan except i created a hot water bath in my crockpot and once the chocolates were melted and colored, i put them in food safe bottles i bought a few years ago for hot ice cream toppings to use with a banana split bar... they are microwave safe and high temp safe to a degree... they are actually designed to be put in a water bath to keep the toppings hot, so it worked for my chocolate too... the water bath kept the chocolates at the perfect temp and when i needed that color, i just pulled it out, screwed on my tip adapter and tada... we have angry birds... they are awesome and i will definately do chocolate more often!
