If you wish, you can prepare your Cocktail glasses with sugar, as indicated in the notes below.
In each glass, pour the Rum or Bourbon.
Add the ice cubes then the cider and ginger beer.
Decorate your glasses and enjoy immediately.
Notes
If you also want to add a small crown of cinnamon sugar, simply pour a little syrup (liquid cane for example) into the bottom of a plate, then dip the rim of each glass. Let drain upside down, if necessary.In another plate, mix the sugar and cinnamon powder. Then also dip the rims of the glasses. The cinnamon sugar will stick to the syrup, and that's it, that's it!
