Equipment
- 1 Citrus juicer
- 1 Tall glass
Ingredients
For the Grapefruit Soda
- 1 large grapefruit juiced -- about 4 oz fresh grapefruit juice
- 1 tbsp honey or simple syrup; adjust to taste based on grapefruit tartness
- 8 oz cold sparkling water divided between 2 glasses; high-carbonation brand
- ice as needed
- grapefruit slice for garnish, optional
Instructions
Prepare the Grapefruit Base
- Cut the grapefruit in half and juice both halves. You want about 4 oz of fresh juice for 2 glasses. Do not use bottled grapefruit juice -- it has added sugar and a cooked taste that overpowers the fresh citrus character.
- If using honey, stir it directly into the fresh grapefruit juice while the juice is at room temperature. Honey dissolves easily in juice without heating. If the honey is very thick, warm it for 10 seconds before stirring.
Assemble Each Glass
- Add ice to each glass.
- Pour 2 oz of the grapefruit-honey mixture into each glass over the ice.
- Pour 4 oz of cold sparkling water over each glass. Stir once gently from the bottom and serve immediately with a grapefruit slice if using.
Notes
Pink grapefruit is sweeter than white -- adjust honey down slightly if using pink.
For a more complex drink, add a pinch of salt and a few leaves of fresh mint.
Keep the grapefruit base (without sparkling water) in the fridge for up to 2 days.
