I got 6 about a year or two ago at Sur la Table (in Lincoln Park). I asked a salesman if they had them but he didn't know what they were. So, I decided to search thru the various molds on the shelf myself and found them. They were tucked way in the back.
As an aside, does anyone know of any bakery/patisserie in Chicago that sells cannele? I tried Vanille a year or two ago and they obviously knew what I was asking for but don't sell them, unfortunately. In general, I find that very few people know what cannele are--they always think I am asking for cannoli and then direct me to the nearest Italian bakery!
