No substitute??? Denied!!!
I was in the mood to make cookies after such a long and annoying day. Sooo... I am adding and mixing and cleaning until... "3/4 tsp baking soda." I'm singing to myself and going to the cupboard where it is kept and !!!!! "NO BAKING SODA??? DENIED!!!!!" So I think to myself, "I wonder if there is a substitute for baking soda? Hmmm..." I google and research. Result: No. Damn. Oh well, I think I'll make some brownies.
