Preheat the oven to 425°.

In a large bowl, mix together the dry ingredients and herbs.

Cut in the shortening until the mixture resembles coarse crumbles.

Add the buttermilk and stir using a fork until a soft dough forms.

Turn out the dough onto a floured surface and knead about 20 times.

Roll or pat the dough to ½-inch thickness and then cut with a biscuit cutter.

Place the biscuits on an ungreased baking sheet and bake for about 10 minutes or until done.
