Dot (1937 Café Royal)

Chill a cocktail coupe glass by filling it with ice or placing it in the freezer.

Prepare an orange zest twist for garnish.

Combine the gin, sherry, apricot liqueur, and curaçao in a mixing glass.

Add ice and stir the mixture until well-chilled.

Fine strain the cocktail into the pre-chilled coupe glass.

Express the orange zest over the surface of the drink, then place it as a garnish.
