Says creator Katie Nelson, a bartender at the Columbia Room in Washington, D.C., "The Back and Forth is an example of a cocktail that starts out with one thing in mind and, after tasting and tasting, becomes something entirely different. We began with the idea of doing a sparkling version of an El Presidente (rum, orange curaçao, vermouth, grenadine) but that didn't work for us, so we changed it. We arrived at a cocktail that is floral and lightly sweet with an herbaceous finish. The bubbles lift the aromatics and provide great acidity. This is a cocktail born to be paired with food. We served it with foie gras French toast and a tomato marmalade."
Combine gin, honey, and chartreuse with ice and shake until diluted. Strain into chilled cocktail coupe. Top with champagne. Garnish with lemon peel and lavender wand.
