I'm not a choc chip girl myself, I'm one of a rare few who looks for the ones with less choc and more sugar biscuit. The demerera makes all the difference in that regard, a lovely crunch that you would otherwise not have. I reduced the chocolate a little (in a half batch only two blocks of lindt one dark and one milk choc - rather than 3) and they were/are perfect.
We packaged a little batch to thank some friends for a lovely play date, but otherwise I know there will be lack of takers here. The salt too, really surprisingly a lovely foil to the sweetness.
