Seems like harvestgirl is making money off of salty vinegary sandy dirt that nobody can eat! Mine is going in the trash as well. I got my white dirt from goodoledirt.com . If you like the smooth white dirt, theirs seemed pretty good. Very smooth with no grit. I prefer gritty and earthy so I still have what I got from them. I don't know if I'll ever grow to crave it, but I will try it from time to time. My favorite so far is the red soil cake from Mavu Seller.
I haven't read a post yet were any one was able to eat eat her clay.
