This is a cookie from Dorie Greenspan's around my french table. You can't tell the scale from my photo but this is one large cookie rather than one of many. It is supposed to be about 5 x 11 inches, but I think I just skipped to the 1/4 inch thick part in the instructions. It is closer to a square than a rectangle, isn't it? She says in the introduction that the cookie is undeniably salty, and that now and again, you can even feel the salt on your tongue. This grabbed me. I love salty sweets.
This cookie is supposed to be made with sel gris, otherwise known as grey salt. Unfortunately, I did not remember until after the cookie was baked that my Dad sent me some grey salt sometime last year.I ended up making the cookie with kosher salt instead. This left it unnoticeably salted. I might would increase the kosher salt to two teaspoons if I made it again without grey salt.
I love the way the cookie is designed to be broken into shards at the table. It was delicious, even if it wasn't done perfectly. I will try it again soon. This time with sel gris and really good butter.
