An incredible all-timer of a cocktail. My personal spin prefers using 1 oz Plantation Grande Reserve, 1/2 oz Smith & Cross, 2/3 oz Cocchi Storico (and leave out the Bianco, having its ratio filled by the Cocchi Storico), and keeping the rest of the recipe list intact with the 2/3 oz Dolin Dry and 1/3 oz Curaçao, with grenadine and bitters to taste.

I find a homemade grenadine (with the proper hits of orange blossom water) really makes this punch above-weight as well.
