For a co-worker's birthday, I made the Cook's Illustrated blueberry muffin recipe. The muffins looked beautiful and were very good, though still not quite as good as a great bakery muffin. The batter was a little less sweet than I'm used to, and the texture a bit more fluffy/creamy. I also made a note to add a few more blueberries next time--maybe a full pint instead of 1.5 cups. Still, they were quite good for homemade, and they were a big hit at the office.
