Equipment

  • 1 Cocktail shaker or a large sturdy screwtop jar
  • 1 Jigger for accurately measuring the ingredients
  • 1 Strainer or sieve

Ingredients

  • 40 ml Rum Spiced, dark or amber all work well
  • 10 ml Lemon juice
  • 10 ml Lime juice
  • 10 ml Honey
  • 15 g Egg white

To Garnish (optional)

  • Dried orange
  • Angustoras bitters

Instructions

  • Measure all liquids into the cocktail shaker.
  • Secure the top and shake hard for 30 seconds.
  • Now add a large handful of ice to the shaker and shake well for another 30 seconds.
  • Strain into a serving glass and garnish as desired - a few drops of Angustoras bitters scattered on top of the egg white foam look great - each droplet can be pulled into a pattern using the end of a cocktail stick.

Notes

  • If there's time chill your serving glass or place a few ice cubes it it while you make the drink, then discard them when ready to serve. This helps ensure the drink is served refreshimngly ice cold.
  • Use a cocktail jigger to get accurate measurements. Cocktails are finely balances beauties and guessing or using approximate measures is not the best approach to take when mixing them.
  • Don't forget to shake the drink twice - first without ice (the dry shake) then with ice (the wet shake). It's the best way to create that creamy top.
  • Shaking without ice first also ensures the honey gets mixed into the drink rather than solidifying at the bottom of the shaker due to the coldness of the ice.
  • Use plenty of ice in the cocktail shaker. This helps chill the drink and dilute it.
  • The Angustoras bitters garnish is optional. Alternatives, such as a twist or lemon or lime peel work well too.
 
Make a vegan rum sour
There are 2 ingredients in this rum and lemon cocktail that need to be replaced to make it into a vegan rum sour.
In place of honey use maple syrup as an alternative. It has a lovely depth of mellow flavour that also tallies pleasingly with rum.
You'll also need to use aquafaba into the cocktail mix in place of the egg white. It's vegan and makes an acceptable substitute for those hoping to achieve that enviable foamy layer on top of their rum sour.
