If you love a light, refreshing cocktail, this highball is about to be your new favorite. The guava nectar adds a fruity sweetness that pairs beautifully with the smooth Japanese whisky.
Prepare the simple syrup first. In a small saucepan, add sugar and water. Cook over medium heat and stir until sugar is melted. Remove from heat and cool completely. Transfer to an airtight glass container and chill in the fridge for at least 2 hours.
Place guava nectar and club soda in the fridge to chill for at least 2 hours. If you can want, you can also chill your serving highball glass (8 - 12 ounces) in the fridge as well.
Rinse lemon under water throughly and pat dried with paper towel. Set aside.
In the highball glass (8 - 12 ounces), add ice cubes. Pour in whisky, guava nectar and simple syrup. Stir until blended. Add club soda and give a quick stir.
Using a vegetable peeler or sharp paring knife, peel 1 thin strip (about 2 x ½ inch) from the lemon, trying to get only the yellow part and avoiding the white pith. Hold the peel over the drink with the shiny side facing down, then pinch to release the citrus oils over the drink. Rub the peel around the rim of the glass, then drop it in.
Serve immediately.
Notes
Leftover syrup can be stored in the fridge for about a month. It can be used in other cocktails, coffee or tea. If you want, you can definitely make more syrup. The ratio is 1 part water and 1 part sugar.
Guava nectar that I used was from Trader Joe’s. It may not be available all year round, but there are many other options in supermarkets. I recommend using nectar instead of juice. Nectar has a stronger flavor than juice, so you can use less without diluting the drink too much.
Once you added the club soda, just give a quick stir. Stirring too much could reduce the carbonation.
