Berry coconut water slushie
Two ingredients. Tastes like a holiday, behaves like an electrolyte drink.
Frozen fruit blended with liquid makes a slushie without any ice, which is the whole trick — ice dilutes as it melts, frozen fruit only gets more flavourful.
Coconut water instead of milk or juice keeps it light and brings a genuinely useful amount of potassium. Two ingredients, ninety seconds, and it reads as a treat rather than a health drink.

Ingredients
Method
-
Use them frozen
Straight from the freezer, no thawing. Thawed berries make a thin smoothie; frozen ones make a slushie. This is the only step that really matters.
-
Blend in bursts
Pulse rather than running the blender continuously. Continuous blending warms the mixture and you lose the texture you are trying to build.
-
Add lime and serve
Lime juice at the end, then straight into glasses. It softens within about five minutes, so this one does not wait.
Worth knowing
- Frozen berries are cheaper than fresh, available all year, and better for this. There is no version of this recipe where fresh is an upgrade.
- If the blender struggles, add coconut water a tablespoon at a time rather than all at once.

A dessert-adjacent drink that happens to carry real potassium, almost all of it from the coconut water rather than the fruit. No added sugar — the 10 g a glass is what the berries came with. Light on sodium, so add the pinch of salt from the variations if you are drinking it after sweating rather than instead of pudding.
How this was worked out: Summed from USDA FoodData Central: 240 ml unsweetened coconut water (46 kcal, 600 mg potassium, 250 mg sodium, 60 mg magnesium) and 200 g mixed berries (about 100 kcal, 20 g sugar, 230 mg potassium), plus lime juice, divided by two servings.
Variations
- Add half a frozen banana to make it creamier and considerably sweeter.
- A pinch of salt turns it into a genuine post-exercise recovery drink.
- Swap the berries for frozen mango for a tropical version.

Why frozen berries rather than fresh plus ice?
Ice melts and dilutes; frozen fruit does not. Using frozen berries gives you the slushie texture and full flavour at the same time, where fresh fruit plus ice gives you a weaker drink that gets weaker as you hold it.
Can you make it ahead?
No — it softens within about five minutes and separates soon after. What you can do is weigh the berries into bags in advance, so making it is just tipping a bag into the blender.
