pot roast and mashed potatoes

it feels like fall around here (though someone in dublin told me i needed to call it "autumn" - always), so i made a meal that works in cold weather - a pot roast. i haven't made one of these in a long time since it takes all day, but a little bit of comfort food was great on a chilly evening. (and i used tapioca flour in place of the wheat flour i would normally use to thicken things up.)
