Cooling melted sugar quickly
How exactly are you making them? This might affect the answer.

I assume you're using some sort of mold. If that's the case, plunge the mold into an ice bath, but don't completely submerge it. Assuming your mold is metal (molten sugar is hot!) they will cool rather rapidly although I can't give you an exact time.

In general, an ice bath is the way to go for rapid cooling. You could get it a little cooler by adding a generous dose of salt to the ice bath, but meh I think you'll only shave a few seconds.
