With all the juicing I've been doing lately, I've been attracted to cocktails with fruit. This is another Pinterest find from the website Bar None.  It was a solid recipe and I only have two tweaks: I would make this drink with regular vodka instead of blackberry flavored vodka.  
The flavored vodka added a syrupy element I didn't care for, 
and I enjoyed round 2 with the regular vodka a bit more. I also added more mint leaves so 
I could get a stronger mint flavor.

Blackberry Pineapple Smash Cocktail

5 blackberries
8 mint leaves
1/2 agave nectar
1 1/2 oz. vodka
1/2 oz lime juice
1 oz pineapple juice

In the bottom of a shaker, muddle 4 blackberries and 8 torn mint leaves with the agave nectar and lime juice.  Add the other ingredients and ice and shake vigorously.  
Strain into a glass and garnish with a spring of mint and a blackberry.

Cheers! XO Martha
