Martinez (variation 3)

1¼ oz Hayman’s Old Tom Gin
1¼ oz sweet vermouth
¼ oz maraschino liqueur
¼ oz Fee Brothers Orange bitters
a lemon peel for garnish

Stir well with ice. Strain into chilled martini glass. Garnish with a zested lemon peel.

Fee Brothers Orange bitters isn't especially bitter; perhaps use slightly less bitters if you're using something else.
