What is a classic New York cocktail with vodka, elderflower, and raspberry, starting with 'A'?

Based on the provided cocktail information, none of the cocktails directly match your desired criteria of including vodka, elderflower, raspberry and starting with an 'A' as a classic New York cocktail. Most of the cocktails listed here are fruit-forward, vodka-based drinks with a berry accent, and though delightful in their right, none incorporate elderflower nor have names starting with 'A'. The Raspberry Martini, with its sweet and fruity notes, or even the Chambord Cosmopolitan, with its raspberry liqueur, might suit your berry and vodka preference, but they still lack elderflower.

For the exact cocktail you're looking for, you might want to consider searching beyond the list provided or adjusting the requirements to find a new favorite. It's possible a specialty cocktail or a lesser-known recipe could fit your description. In New York City's diverse cocktail scene, bars often have their unique creations that might align closely with your request. If you have the ingredients at home, perhaps experiment with creating your version of the desired cocktail!
