some years ago my dad was diagnosed with a weird case of t1 diabetes that didn't present itself in any way until he was 60; he's considered an anomaly for it. one of the very few foods he's refused to give up is the apple crumbles/tarts he liked to get from stores, so last year I decided to try to make an oat-y crumble that wouldn't impact his blood sugar as much. when I make it he kindly lets my mother and I have a piece before promptly eating the rest straight from the pie dish himself.
