This is a guest post from Dave, cocktail creator extraodinaire.
Here's a cocktail that I made up for a Preakness party. A traditional Black-eyed Susan is a punch; I was going for something a little more sophisticated but keeping with the theme of these lovely yellow-and-black flowers.
2 oz. vodka
1/2 oz. lemon juice
1/2 oz. St. Germain
1 tbsp simple syrup
Place ingredients in a cocktail shaker with ice; shake until frigid. Strain and pour into a chilled cocktail glass.
Cut out a twist of lemon peel over the glass. Wrap it around a toothpick and impale a blackberry with the toothpick. Drop garnish into glass.
If this is too sweet for you, back off the sugar syrup to 1/2 tbsp. For a fruitier variation, try Cointreau or Grand Mariner instead of St. Germain.
