I have sampled the almond croissant by Elizabeth Street Cafe in Austin, and I found them highly satisfactory.
My path was indirect, however. Although I have been to the cafe, which specializes in Vietnamese food with a Frenchy twist, I actually sampled the croissant at the (sadly) now closed trailer La Boîte. It was a very cute spot: a trailer on a hill selling macarons, coffee, croissants and sandwiches. Here is a photo by Aimee Wenske and Jeff Kauffman.
I had visited after it was suggested by a reader; me and a buddy stopped by the pre-funk before breakfast at 24.
Which takes us back to that almond croissant.
It was supplied by the Elizabeth Street Cafe, I learned, and it was a fine specimen. A crackly exterior that did that nice shatter-crunch thing that a good croissant should do, in your mouth, not in your hand. A rich, almond-y flavor that permeated each bite. Crunchy almonds on top to give it a texture contrast with the smooth, slightly gooey interior. Overall, a very satisfying croissant experience.
That's all. Go get one yourself.
You can't enjoy one at La Boite anymore, but go right on over to Elizabeth Street Cafe, 1501 S. 1st Street, Austin; online here.
