I have my own additional allergies and preferences so I skip the buttermilk completely, substitute honey for agave nectar, and use 3/4 tsp baking soda + 1 1/2 tsp cream of tartar (OR you could use 1 tbsp baking powder) instead of yeast. Without yeast it needs a couple more minutes baking time than it does when I make it with yeast. You can use all different kinds of spices and it is yummy any way you make it. Tastes like a whole grain type of bread. Even my gluten-eating family likes it.
