Free food is the best food, which is why I love this time of the year in the Pacific Northwest. We have the perfect weather for blackberry growing. It's not too hot, not too cold.
This is a picture from a bush growing along the side of the road by my house.
Blackberries are everywhere this time of the year.
I can't pass up free stuff, so I have been picking and freezing for the past month.
I'm sure this tip is nothing new, but if you put the fruit on a cookie tray, then freeze it flat for about 2 hours, then bag it, your fruit is easier to use when you are ready for it.
I use blackberries in smoothies, in pancakes, and in blackberry cobbler.
