Cherry juice provides an interesting counterpoint, balancing the bite of the mezcal without over-sweetening.
This is one for the bucket list...and don't forget the salted rim.
3 oz mezcal
2 oz tart cherry juice (I found this at target, Cherribundi brand)
1 oz Grand Marnier
Juice of one lemon
1/4 oz agave nectar
Freshly ground black pepper
Mix all ingredients together in a shaker over ice. Shake very well and pour into a salt-rimmed glass.
Bonus points if you use citrus salt.
