..... When I tasted the flours straight out of their packages, I noticed that the tapioca flour was the culprit......
I would acquire another package, perhaps another brand of tapioka starch flour and taste it. If the taste doesn't agree with you, I would try using a combination of potato starch, corn starch, and arrowroot starch.
I use a combination of white rice flour, brown rice flour, sorghum flour, bean flour, tapioka starch, potato starch, and corn starch for all my baked goods. Approximately half flour and half starch.
