Yeah, it is sort of like shake n' bake... we use S&B all the time for pork chops! (and I helped!)... LOL!
But this is more like real southern fried chicken... without all the mess!
we find powdered buttermilk right next to the Carnation Powdered Milk... (usually the baking isle)...
easy to find... at least in NY/NJ... all the supermarkets have it...
I have found it at King Kullen, IGA, Shop-Rite, Stop & Shop, Hannaford, Price Chopper, Waldbaums, Pathmark & A&P...
or you can find it at the source:

I have found it makes a good roux for chicken/turkey gravy too!
I usually mix it 1/2 & 1/2 with GP Flour...
