An elegantish concoction, employing stuff you might find on the sideboard at any English country house—except with a lot more ice. The leanness of the gin and the dry sherry are compensated, but not overcompensated, by the lushness of the port, with the bitters tipped in to remind everyone to behave.
2 ounces gin
1 ounce dry sherry
1/2 ounce ruby port
2 dashes Angostura bitters
To finish: lemon peel
Stir and strain into a chilled cocktail glass; twist lemon peel over the top.
