A list of 25 sources. Road trip anyone?
I've been to a few of these and would recommend them highly. They are all different and all worthwhile:
Jenni's Splendid Ice Creams
Toscanini's (there are so many good places in the Boston area:-)
Molly Moon Ice Cream
Moomers Homemade Ice Cream (they do know how to make a milkshake)
Graeter's (not in the store, but the packages - really good though)
Here is a recent satisfied customer cleaning the dasher - she was very enthusiastic. This was based on freshly picked raspberries. In the end ice cream is about happiness.
