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.

I purchased these because they do not contain dairy, soy or corn.  Well, in addition to being dairy free, soy free.... they are FLAVOR FREE!  Absolutely horrible dry tasting bars.  First words out of my mouth were "tastes like dirt" so that's what I'm going with.  DO NOT WASTE YOUR MONEY.

I love this tea which has a deep cinnamon aroma and taste.  It's equally good as an iced tea.  Full marks!
