part-time lover

1 1/2 oz Blanco Tequila (Cimarron)
1/2 oz Aperol
1/2 oz Elderflower Liqueur (St. Elder)
3/4 oz Lemon Juice
2 dash Angostura Bitters

Shake with ice, strain into a rocks glass with ice (coupe glass sans ice), and garnish with a grapefruit (orange) twist.

Two Mondays ago for the cocktail hour, I turned to Imbibe Magazine online where I had bookmarked the Part-Time Lover created by Jon Weimorts at Los Angeles' Idle Hour. Indeed, the combination of Aperol, elderflower, and lemon reminded me of Paul Clarke's Dunniette and Josh Childs' Shaddock. Here, the spirit was tequila with an added spiced complexity from Angostura Bitters.
While the recipe prescribed an on-the-rocks presentation, I was more in the mood for an up drink and served it as such; I was also out of grapefruit, so I switched the twist identity to orange. With this change in garnish, the orange oil brought out the Aperol aroma on the nose. Next, lemon juice and Aperol's orange combined to generate an almost tangerine flavor, and the swallow gave forth tequila, rhubarb, and elderflower flavors with clove-driven bitters on the finish.
