I had some blackberries that had seen better days in my fridge. I hate wasting good produce so I threw them in my blender with a little water and some sugar. You can do this with any berries and the results are delish. It's great over ice cream, pound cake, and adds a special touch to cocktails. I poured the puree through a sieve because blackberries have so many seeds. You can skip this step if the seeds don't bother you.
Store it in the fridge in an airtight container, notice my fancy Snapple bottle. I'll give you a hint on one of my favorite ways to use this puree'. If you're wondering why I didn't take a photo once I filled my glass, I'll just say I was preoccupied!
