Gluten-free apple pie is the height of comfort food for many people. I'm usually a crust rather than crumb fan, because I find most crumb toppings overly sweet. Not the case, here. Perfectly sweetened. And the filling is neither heavy or gluey. This is one where the apples play their rightfully starring role. In fact, given the overall excellence of the pie, this may win over many top-crusters to the crumb team. Well done, Gillian's!
