I stopped by Tartine today at about 2:30. Nice day, and there was no line at all! I was excited to see that they had cannele. The person behind the counter told me it was the first time they had made cannele since Tartine was located in Mill Valley. They are $2. They contain orange zest. They aren't huge by any means, but true to Tartine form, they are substantial. The inside consistency is pretty good but a tad gummy, and I think they are a bit too sweet. I like to taste the egginess. The crisp outer shell was perhaps not carmelized/crunchy enough. Maybe these should have been left in the oven a minute longer. In general, pretty good, though.
I think of cannele as a fairly uncommon item, but the gentleman behind me in line says he sees them everywhere. He named Mission Beach Cafe and somewhere else (wish I could remember). I know Bay Bread stores have them.
