Say \"Whiskey Sour\" and most people picture a drink with an umbrella and/or a dyed-red cherry. Instead... Mix: 2 oz Ardbeg Single-Malt Islay Scotch 1 oz fresh lemon juice 1 squirt Blue Agave nectar Stir to combine (or shake) Garnish with 1/4 frozen lemon instead of ice. THAT! My friends. Is a true Whiskey Sour.
