Here’s one from the wonderful bartender Jim Meehan of PDT (Please Don’t Tell) in New York City. This is a great way to introduce people to vermouth who might be afraid of it. Dolin Blanc is probably the best sweet white vermouth available now, and will knock your and your guests’ socks off, but you can also use Martini & Rossi Bianco.

The Astoria Bianco
(by Jim Meehan, PDT, New York)

3 ounces gin.
1 ounce sweet white vermouth (Dolin Blanc or Martini Bianco).
2 dashes orange bitters.
1 orange twist.

Fill a pint glass with ice. Add gin, vermouth and orange bitters; stir well. Strain into a chilled coupe and garnish with the orange twist.

This is lovely.
