I liked reading about the Fistful of Dollars cocktail. In mixel, the little quote explains that the bar hated it by the end of its run because it was so popular. I had a grapefruit today, was really craving mezcal & grapefruit, was out of orange liqueur and as anyone who has hung around this thread probably knows, am a sucker for any fancy whiskey sour.
2 oz bourbon
1 oz lemon juice
1 oz grapefruit juice
3/4 oz mezcal
1/2 oz Campari
3/4 oz cinnamon bark syrup
2 oz Crodino
Shake together first 6 ingredients then add the soda and pour it a couple of times between the shaker cups to combine and froth. Pour over one big ice, garnish with grapefruit peel.
I think this would also highball beautifully with some grapefruit soda (instead of grapefruit juice and Crodino, probably increase the Campari) , the mezcal instead of orange is an improvement, to my palate.
