Was looking through my pantry and I found some instant biscuit mix that is still good by date. When I tried making a batch of the mix, the dough did not rise at all. I made something that resemble a brick.
I was curious if I could add some double action baking powder to the mix would bring the mix back to life?
If so how much would I add? 1/4 TSP?, 1/2 TSP?
All I have on hand is double action baking powder.
