The Rusty Nail is made by mixing Drambuie and a blended scotch. Single malts can be used but I usually reserve that for neat or on rocks.
1 1/2 oz Scotch
3/4 oz Drambuie (Drambuie is a scotch liqueur, heather honey, spices and herbs)
Mix in an Old-Fashioned Glass filled with ice, Stir and serve with a lemon twist. Enjoy!
