Blueberries are best straight from the bush, but a blueberry muffin fresh from the oven is nothing to sneeze at. However, blueberries can sometimes sink to the bottom of the soggy muffin, along with your dreams. The solution is simple. Just coat the blueberries with a bit of flour before plopping them in the batter. According to the good folks at The Kitchn, this will absorb some of the liquid released by the berries and keep them in place until everything is set.
