Blackberry Puree

I am trying to recreate a blackberry martini I recently had at a local bar. The first step is to make blackberry puree. I’ll post the actual drink recipe once I get that hammered out, but here’s the puree in the meantime.  I tried to find this ingredient online so that I didn’t have to make it, but I had a tough time finding any that was of a reasonable quantity and price.

This is an easy process, the longest part is waiting for the frozen blackberries to thaw. I also divided the final puree into small plastic containers so that I can just pull out a portion that’s just the right size for one drink so that I don’t have to thaw it all each time.  From on 16 ounce bag of frozen blackberries, I got a similar liquid volume of puree. I’m planning to also use this recipe with raspberries to make a raspberry martini. Yum!


Makes about 16 ounces.


16 ounces frozen blackberries, thawed
6 tablespoons sugar


  1. Puree berries and sugar in blender.
  2. Strain to remove seeds (Don’t skip this step, there are a lot of seeds!).
  3. Refrigerate for up to 2-3 days or freeze.
