I'm not so sure why those popsicles aka ice on a stick are called as "es goyang" since "goyang" in Indonesian language means shaking. Uhmmm.... do they need to shake the ice or they shake their body while making the ice? hehehe... Well, probably it's just a matter of a name :)
There are many flavors, i.e: mung beans, red beans, avocado, coconut, etc. We even can ask the popsicle to be deep into chocolate and sprinkle it with ground roasted peanuts
Dry ice is provided for those who don't want to eat the popsicle directly (it's for take-out purpose).
I had the avocado es goyang and it costs me only less than US 20 cents :)
Don't be surprised if the popsicle tasted salty and salty because instead of made by milk, it's made from coconut milk with a pinch of salt as the basic ingredient.
