1/4 to 1/2 ounce Rosemary Simple Syrup
1 ounce Limoncello (lemon liquor)
1/2 ounce fresh lime juice
3 dashes Angostura bitters
Prosecco (or other dry sparkling wine)
Fresh rosemary sprig (for garnish)
Lemon rind curl (for garnish)
 
Note: You may have to adjust the amount of syrup, depending on how dry your sparkling wine is. Use the full half ounce if using a very dry sparkler.

Shake the first four ingredients in a cocktail shaker with ice. Strain into an 8–ounce cocktail glass and fill the rest of the glass with sparkling wine. Garnish with a rosemary sprig and lemon rind curl.
