I moved recently and couldn't find my family's cherished pie crust recipe! After some searching, this is the one! My mother and grandmother swore by this crust, and locally gave credit to a gal named Opal Kosmata. Don't let the vinegar turn you off to trying this crust, whatever it does in the recipe makes it perfect. In the past, when I have been low on shortening, I have substituted a little butter to make up the 1 1/4 c., and it came out just as great. Thank you for posting this crust recipe, it was a lifesaver!
