I will actually be making a Martini glass this week. I will try to take pictures and post them to see how it comes out.
I did try it with puchasing the martini glass chocolate mold, then putting wet sugar in it and drying it, didn't work, the stem is so think that it kept breaking. So I actually did the upper part of the glass that way 1/2 and 1/2, dried them, and then put them together with melted chocolate, and dug out the center of the glass to put colored RI in it. Worked pretty cool, but I had to keep coming up with ways to keep the skinny little stem from breaking apart.
I will let you know how the "mold" thing works out.
