When I first went to Singapore, my favorite dish was the ice kechang desert. (There are similar versions in the Phillipines, Thailand, Malaysia etc., but Singapore's is by far my favorite.)
I live in Los Angeles, and I've never seen it anywhere. Again, pale copies at a few Indonesian places, but nothing approaching the sublime tastes like I found in Singapore.
I'd love to try making it at home, unless the ingredients are too difficult to get/make. If I can get even close to the recipe, I'd even buy a snow-cone machine, just to get the finely-shaved ice that is necessary.
