(I´m Lebanese too!) In warm weathers such as Lebanon or Spain where I live, the best is to use the Carma Ticino, it´s a fondant specially created for ho, humid and tropical climates. My life has changed since I discovered it!!!
It is made by the company Callebaut, just google " Carma massa Ticino! and it will lead you to their page, they are sold world wide. I am sure you will find it in Lebanon, it´s a cake decorator from Dubai who gave me the name and she gets it there.
