My Grandparents used to live in a cabin on a lake in the woods in New Hampshire. They had a couple of huge wild blueberry bushes that grew hanging over the water. Every Saturday night Grandma would put on her waders and pick a bucket of sweet wild blueberries. On Sunday morning she would bake these. When I got up, they would be sitting warm in a basket, covered with a towel. These are the best muffins I have ever had, by far. I don't even bother looking at other blueberry muffin recipes- these melt in your mouth, are lightly sweet and full of blueberry flavor- they are literally perfect.
