Coming from a chef, I was more than pleased with that comment.
Many people struggle with ideas for gluten free desserts, and this is a really simple pudding that anyone can make. A good opportunity to use up all those windfall apples in the autumn or fall, perhaps? Who can resist warming comfort food like this?
Using rice flour in this recipe gives additional crunch to the topping. Normally I steer away from this flour, as for many recipes you don't want that texture to be apparent in your baked goods.
