1/2 oz Aperol
3/4 oz Vanilla Passion Fruit Syrup (*)
3/4 oz Lemon Juice
1 dash Peychaud's Bitters
Shake with ice and strain into a Collins glass filled with ice. Garnish with a floated lemon wheel, and add a straw.
(*) I have used equal parts of passion fruit syrup and vanilla syrup to mimic this all-in-one syrup (perhaps use 1/2 oz each here). Or go all passion fruit syrup with a few drops of vanilla extract.
