This is a couple minor variations on a drink I saw on Jameson's match your drink to your moustache promo for Movember (my pre-movember moustache matched this one pretty closely ....). Anyway I subbed scotch for the Jameson's and cut the sweetener in half (and tinkered with the garnish).
1.5oz Monkey Shoulder Scotch
.5os fernet branca
.75oz lime juice
.5oz agave syrup
Fresh mint (for drink) a whole bunch of small leaves
More fresh mint and lemon balm (for garnish)
Add all ingredients except garnish to shaker and dry shake vigorously. Add ice and shake again. Strain (double strain if finicky) into ice filled, chilled rocks glass
