Muddle well, making sure to mix all ingredients well together.
Add the rum to the glass.
Fill the glass with ice, leaving a little room at the top for soda water.
Top with soda water of your choice. In this example, I used Spindrift lemon to bring out the flavors of the citrus and kiwi.
Stir the cocktail well to distribute the ingredients, then garnish with a slice of kiwi and a dehydrated lime wedge.
Notes
For larger batches:If you are making a large batch of this cocktail, you can prepare them all in one large pitcher, then stir well and serve.Leave the soda water out and instead pour a little on top of each glass as you pour the base of the cocktail into glasses of ice.
