Due to an editing error, in the first-edition printing of Drinking French, the metric conversion for the dry ingredients isn’t correct. The metric amounts should be (in bold):
1/2 cup (70g) all-purpose or corn flour
1/2 cup (95g) stone-ground cornmeal
These have been corrected in subsquent editions of the book.
