I gave gluten-free biscuits another try. These were indeed pretty good. They were delicate and could crumble if not careful but were not dry or grainy. A thumbs-up from the family. I liked them so well I have made them twice.
What did I change to the recipe? I did not use the brown rice flour mix as suggested in the recipe because I did not have all the ingredients on hand. I just used plain brown rice flour instead. The only other thing I changed was that I used Rice Milk instead of coconut milk.

As always, Happy Baking!
