One of my all-time favorite cocktails is The Solution at River & Rail. It's a grapefruit margarita with agave nectar and finished off with a cinnamon and sugar lined rim. It's heavenly.

For awhile now, I've been wanting to recreate this little masterpiece of a cocktail and well, I did it. After some major trial and error (I spilled part of the drink while shaking and pretty much got grapefruit juice everywhere) I finally got it on lock. If you're craving a fresh end of summer marg, this one should be your go-to like yesterday.

1.5 ounce silver tequila
1 ounce Cointreau
1 tablespoon agave nectar
3/4 fresh squeezed lime juice
1/2 fresh squeezed grapefruit
1/2 fresh squeezed lemon

Directions:

In a martini shaker, add lime, grapefruit, lemon and agave nectar.

Add Cointreau and tequila. 

Add ice to shaker. I also add the fruit to the shaker.

Shake well.

In 2 glasses, muddle grapefruit and lime. Add ice.

Strain mix over ice. 

Side note:
This was a major trial and error drink. I give bartenders some major props because I definitely had to add a little more of this and a little more of that to get it just right. However, the end result was perfect!
