Mad March Days

Select and pre-chill an Old Fashioned glass.

Prepare a garnish by twisting a strip of lemon zest.

Stir the bourbon whiskey, single malt Scotch whisky, amaro, and Becherovka liqueur with ice until well chilled.

Strain the mixture into the glass filled with ice, ideally over a large cube or chunk of block ice.

Express the lemon zest twist over the cocktail to release its oils and use it as a garnish.
