I only had 15% triple sec, so I substituted 40% Cointreau. Delicious nevertheless! This seems very similar to the Dubliner and James Joyce cocktails -- they are all riffs on a Manhattan, but with orange liqueur substituted for some of the vermouth, and perhaps some extra aromatics.
Very nice. Orange and whiskey work well together. The single dashes of orange and angostura bitters was perfect. I used Pierre Ferrand’s dry Curaçao but it was still sweet enough. The vermouth and grenadine worked well.
This is so smooth and a outstanding aperitif. Not too sweet, but you can taste all the different flavours in the cocktail. Great colour. Would do again.
