1 1/2 oz. bourbon
1/2 oz. St. Germain
1 oz. juice [good: cranberry cocktail, better: Simply Grapefruit, worse: 100% cranberry]
1 egg white
1 splash fresh lemon juice
Combine in a cocktail shaker. Shake vigorously without ice until frothy. Add ice and shake again, then double-strain into a cocktail glass. Garnish with a lemon wheel.
