Stir with ice, strain over big rock. Float Smith & Cross; twist lemon and drop in.
Ideally use Cuban rum for the base but feel free to experiment with others (Appleton 12 should be great). Miramar is a suburb of Havana; it's also the Wellington suburb where our movie industry is based (and which I can see from my lounge).
Inspired by the Havana, by Giancarlo Jesus of the Hawthorn Lounge.
