Does glutinous rice flour function differently from regular rice flour as a coating?
I haven't tried either but I found this, which seems helpful:

"there is a big difference between the two..where i come from.(malaysia).we use rice flour to make banana fritters (deep fried in rice flour batter thus giving it a crispy crunchy batter) while glutinous rice flour will give a sticky texture..u cant deep fry the batter but its normally used to make sweet desserts where u boil the cakes in boiling water..when they are cooked they will float and voila... "

I found this recipe online that uses egg whites for the coating. The recipe says wasabi peanuts but picture is of wasabi peas.
