Whats the best source of energy when ski touring?

My top energy sources:
Malt Loaf: my personal favourite and always popular when handed around. fruity, chewy and about 80% carb
Dried dates: stick it in the corner of your mouth and chew away whilst putting in the miles.
Bananas: a great natural carbo source, but tend to go mushy after a big fall!!
Energy Gels: taste very sweet [...]
