First of all, grab an old fashioned bar glass and place this on a flat counter space. Add 2 dashes of Angostura or Peychaud’s bitters to this glass.
Next, add the sugar cube, and 1 teaspoon of water to the glass containing 2 dashes of Angostura or Peychaud’s bitters. Once all these ingredients have been added in, use a spoon to gently swirl the mixture about, until the sugar has dissolved completely – make sure there are no sugar granules left, that might add an unwanted graininess to your old fashioned gin cocktail.
Once the sugar has dissolved, proceed to pour in the starring ingredient – 2 ounces of gin. While pretty much any brand will do, you can try to obtain and use Genever or London Dry, in order to make the cocktail a truly unforgettable experience.
Finally, add 2 large ice cubes to the glass, and give the cocktail a gentle stir, in order to mix everything together. Old-fashioned cocktails are known for containing large ice cubes that rattle around in the glass as the drinkers help themselves, so do not pick out the ice.
Your classic and simple old fashioned gin cocktail is now ready. Garnish it in any way you want (although if you are going for a truly old-fashioned look, simply skip the garnishes and keep it plain), and serve chilled.
