Timing wise, you want to form your rolls so that they can start in on their final rise while you mix the crunch topping and let that sit for its 15 minutes to meld.
The crunch mix is odd, I ended up adding more rice flour to get it to the stiff royal icing consistency called for, I don't really know how much, I sort of got frustrated and dumped a bunch in and that ended up being the right amount, magic.
This is another strange part, these snowballs are the rolls after I slathered the crunch goop on them with my fingers, make sure to cover the whole roll with a relatively thick coat, if it's too thin it won't crackle properly and it won't crackle much at all if it's too thick. It is messy. Just a warning.
Bake them up and enjoy. If you need any clarification regarding the crunch topping check out this blog ( I know, I know, this is the third time I have linked to it, but really, it is quite useful)
Dutch Crunch Topping (this is the halved version, should make enough for about a dozen rolls/ one standard batch of bread dough, if there is such a thing)
1 Tbs yeast
1/2 cup warm water
1 Tbs sugar
1 Tbs veggie oil
1/4 tsp salt
3/4 cup rice flour
Mix all the ingredients together, adding more water or rice flour as needed to make it the consistency of a stiff royal icing.
Let sit 15 min.
Slather a good coat on your rolls or bread and bake according to the bread instructions.
