Ingredients
- 300 ml chilled energy base
- 1 tbsp watermelon syrup
- a cream float
- a watermelon wedge
- Ice
Equipment
- 16 oz glass
- Bar spoon
- Measuring jug
How to make it
- Fill a 16 oz glass with ice and pour in 300 ml of chilled energy base.
- Measure 1 tbsp watermelon syrup in — energy bases are already sweet, so start at half of what you think and taste before adding more.
- Stir once, gently, with a bar spoon.
- For the creamy version, float a cream float on top rather than stirring it in.
- Add a watermelon wedge.
- This one is caffeinated by design — check the total before you drink two.
Tips that actually matter
- 1 tbsp of syrup maximum. More tastes like candy.
- Watermelon is delicate — do not pair it with another strong syrup.
- Serve very cold; warm watermelon syrup is unpleasant.
Variations
- Frozen watermelon chiller blended with ice.
- Add 1 tsp of lime to sharpen it.
- Sugar-free watermelon syrup.
