This is the pancake mix we go to when we don't have buttermilk in the fridge (don't think the vinegar trick is worth it so we always do fresh) to make Alton Brown's buttermilk pancake recipe.  This Stonewall mix is a good option and the flavor is the best of any store bought mix by far! It might cost more, but it really is superior to the other prepared mixes.
