During the summer when they’re in season, I can’t get enough of them. I’ll buy baskets of blueberries just for me to eat, all by myself. No guilt. No justification needed (though if you do need a reason, they’re great for your brain and are considered a superfood). Half a basket gets dumped into the morning’s cereal, the rest nibbled throughout the day. We keep bags of frozen blueberries around for pancakes or smoothies; fresh ones are usually just eaten straight. With this blueberry frozen yogurt recipe, you can use either fresh or frozen blueberries, though you might want to lean to the frozen as you are going to freeze them anyway, and the frozen berries are usually cheaper. The tartness of the yogurt seems to just intensify the flavor of the blueberries, and a little cinnamon adds a touch of spice. While the mixture is heating, use a potato masher to mash up the blueberries. When all of the sugar has dissolved, remove from heat. Strain out the blueberry skins and let the juicy blueberry syrup cool for 10 minutes. Cover and chill the mixture in the refrigerator for several hours (or overnight) until completely cold. Serve immediately (it will be soft) or let it firm up a bit by freezing it for several hours.
