retch:
The cookies are turning out... interestingly. I made a batch at xmas and they came out weird too, I thought it was because I cooked them in my friend's convection oven, but this batch is at home, so now I'm thinking the baking soda may be the culprit. Put less in the 2nd batch we'll see how it works out.
retch:
2nd batch turned out really well, though still puffier than expected. The baking soda must be way stronger than usual...
