I was inspired by the a drink from the 1934 Laird's recipe book on EUVS, and I decided to tinker. I recalled the apple brandy-Rabarbaro combination and the apple brandy-Cardamaro one from other cocktails, and I combined all three elements into an Apple Negroni-style equal parts cocktail. For a name, I decided to dub this one after a Yukio Mishima novel called Runaway Horses.
1 oz Aged Apple Brandy
1 oz Cardamaro
1 oz Zucca or Sfumato Rabarbaro
Stir with ice, strain into an old fashioned glass with ice, and garnish with a grapefruit twist.
