Mixed dry is preferred method unless using power m
Dry ground or whole chia (or flax, psyllium, etc) mixes with other dry ingredients evenly and quickly using a spoon. Pre soaking requires a power mixer for lump free results, just like conventional baking with eggs and dairy. I grind as I go, using a cheap Woolworths coffee grinder for only a few seconds. Black and white seeds when ground together give a wholemeal flour appearance. The results are much superior to conventional baking: a delicious taste and great mouthfeel with a moist but not soggy crumb tasting fresh for several days.
