Hey, Goodweed, good idea about the tapioca, this recipe could benefit by it, if you are not inclined to lick the bowl
I purchased a case of flax seed, 12 one pound bags, a while back in hopes that this natural plant estrogen could help relieve hot flashes. So I still have a few bags in the freezer, that is really why I have been adding it to the crisp topping. I have completely switched over to fair trade coffee beans, and when I grind a kilo bag of coffee beans, I also grind a bag of flax seed. I am really just trying to use up some odd ingredients I have lurking in my freezer.
This recipe works very well without the optional ingredients added.
