I'd realise that Singapore weather is really not friendly at all to fondant. The fondant roses that I had made previously started to melt the very next day. I guess it didn't help as well as end April - early May was reported to be the hottest days (33 Celsius) since beginning of the year. Furthermore we're not getting much reprieve until June, which also happens to the the hottest month in the year.
The alternative would be to use gum paste. Although gum paste does have sugar it's really not edible. But it was really easy to work with and mould the roses. Here's some pictures of the end result ... I thought it was so much better than my earlier attempt and will be trying my hand at other creations.
