I can't make proper roti's with wholewheat atta either - I use to just use white and had perfect rot's then MIL arrived and said better use medium or wholewheat atta - so we switched. Now sh'es gone to BIL's and my roti's aint turning out the same!
I haven't changed method or anything!
Does anyone know if you have to adjust anything in the process when using wholewheat??
no change..simply knead and roll out and make roti on tawa..u can even make whole-wheat pooris as well...my sis too uses medium atta being there and she makes perfect pooris with that:)
