I had a craving for ginger + chocolate, so I decided to try this recipe for ginger chocolate chip cookies. I more or less followed the recipe exactly, except I used diced crystallized ginger instead of ginger chips, and I substituted 1/3 cup spelt flour for 1/3 cup of the all-purpose flour. Also, I decided to live dangerously and not grease the (nonstick) baking sheet, and it turned out fine.
When I read the recipe, I wondered whether little bits of ginger would give the entire cookie a ginger flavor, or whether it would only be noticeable when I bit into a piece of ginger (sort of like biting into a raisin in an oatmeal raisin cookie). Happily, the ginger flavor does permeate the entire cookie, and is punctuated when biting into an actual piece of ginger.
The only thing I would do differently when making these cookies in the future is doubling the recipe. I made my cookies a little bit bigger than the ones contemplated in the recipe, so I wound up with about 28 cookies instead of 36.
