I had Tanqueray Sevilla Orange and Cinzano Extra Dry and used the given proportions. It is quite orangey, but I like it! I’ll try it again when I get some unflavored London Dry gin. (I usually only have American style gin, but have been enjoying my Negronis with the Sevilla Orange and perfect martinis with Tanqueray's Rangspur Lime. Both are nice diversions.)
