Last summer I experienced my first gumpaste bow fatality. The cake had been delivered the evening before the event. Humidity was 100%, temperatures in the 90's, and by morning the bow had collapsed. This is bad enough with a bow, but would be awful with flowers that had taken days to make. Is there a recipe or an alternative to gumpaste that is humidity-proof?

The only thing I can think of would be pastillage becuase it dries so hard. Or maybe cold porcelain?

What is cold porcelain anyway? I've seen it in my CK catalog and heard it mentioned here and there. I'm assuming it isn't edible. Is it used the same way as gumpaste and for the same purposes?

I live near the beach, so the air is always humid even when the temps aren't high. GP does not do well in high humidity. I have had much better luck with commercial fondant mixed with tylose powder!

How much tylose to how much fondant?

Sorry I kind of eyeball it... I'd say about a teaspoon for a baseball size chunk of fondant.
