A crusta combines Cognac, triple sec, maraschino liqueur, lemon juice and bitters - peach in our case. Some sugar the rim, though I did not. I got my recipe from Cocktail Party. The crusta is one of the oldest cocktail templates: the earliest sour and an ancestor to the sidecar, one of our house favorites.
The flavor is wonderfully layered. The cherry hit me first but it was the peach for my wife. I accidentally used too much lemon juice - noticeable but it certainly didn't ruin the drink.
