Wanda Lou, give the biscuits another try. I use bisquick all the time and the biscuits aren't that dry. I eat them split in half, hot with melted butter and jelly or honey or with gravy over them. They are the best biscuits I have found. I haven't ever tried eating them cold as I don't like a cold biscuit.

Wanda, GF Bisquick doesn't have any shortening like the regular does. You have to add your own.

Yes, you can use butter and less salt. It's a whole 'nother thread, but sea salt is healthier than regular salt, IMO. I have never baked with kosher salt and I don't make dill pickles any more.

Plain rice flour thickens well, too. That one surprised me.
