Looking at the recipe you listed it seems to me that the problem is the HUGE amount of baking powder¦¦that certainly would make it taste horrible. Peronally I use bicarbonate of soda & something like buttermilk , sour milk or plain yogurt. I don't have an electric machine, I still use my old-fashioned one you heat up on the cooker ring¦.I bought in Holland in thr 1970's & it works splendidly.
However I found this recipe
It's American recipe & it is for an electric machine¦¦I have found Alton Brown's recipes to work well. He uses both bicarb. & baking powder. Have a try with it & see whether it works better. I suspect it will.
Good luck & let us know how it turns out.
PS: I often let mine ferment overnight for a better rise. You can use yeast to do this instead of the other rising agents.
