To celebrate the return of the final season of “Mad Men,” which premiered on Sunday, mix up one of these martinis, inspired by three of the characters on the show, while you’re watching 1960s New York City come to life for one last time.

The Roger

(Classic man’s man with a little dirty side.)

4 oz. Belvedere Vodka

1/2 oz. olive juice

Garnish of blue cheese olives

Combine the vodka and olive juice into a shaker. Shake 10 to 15 times. Strain into a chilled martini glass and garnish with three olives.

The Don

(While still a classic character, Don cuts his own path and does things differently.)

4 oz. Hendrick’s Gin

1/2 oz. vermouth

Garnish of cucumber ribbons

Combine the gin and vermouth into a shaker. Shake 10 to 15 times. Strain into a chilled martini glass and garnish with the cucumber ribbon.

The Betty

(A trendsetter with a wild side)

2.5 oz. Belvedere Vodka

1 oz. Monin violet syrup

2 dashes Fee Brothers Peach Bitters

1/4 oz. Pernod

Garnish of a lemon twist

Combine all ingredients into a shaker. Shake 10 to 15 times. Strain into a chilled martini glass. Garnish with a sugared rim and the lemon twist.
