How thick should snowball syrup be?

Snowball syrup should have a consistency similar to that of pancake syrup—thick enough to coat the back of a spoon but still pourable. Ideally, it should be viscous enough to cling to the shaved ice without immediately soaking through. If it's too thin, it won't provide the desired flavor; if it's too thick, it may not distribute well over the snow. Adjustments can be made by adding water or more sugar to reach the desired thickness.
