I love berries of all kinds, and am lucky to live where lots of them grow. Recently I bought some freshly picked blueberries at a farm stand: they were delicious! Some went into muffins, some on cereal, some were just eaten as a snack. The rest, about a dry quart, I turned into a little batch of jam. You may double the recipe, if you wish a larger batch: the jars make perfect gifts.
