It's probably a little late for berry season in the U.S., but there's always frozen ones.
Here's a recipe for a cobbler that is sooooo delicious that it has become my "go to" recipe for blackberry cobbler, especially since our blackberry vines seem to be over-achievers.
I don't make any changes to the recipe other than adding more blackberries and topping the crust generously with sanding sugar before I put the cobbler in to bake.
The recipe is from the July 2012 issue of Southern Living
magazine. I've been a subscriber for many years and have tried countless recipes from the publication. Everything I've made has been a winner, many becoming family favorites.
