I checked my go-to source hoping for blackberry suggestions beyond simple jam or cobbler and was rewarded with a post from a blogger than no longer posts: foodinjars.com/blog/wha… and a link to blackberry butter csaboxingday.com/2014/0…
If I can collect more than a handful of berries from along our creek next year I'm going to try the blackberry butter and maybe get fancy and try the Blackberry Chambord Jam.
