Refreshing Fruit Smoothie: Watermelon Lime Mint Cooler

Watermelon lime mint cooler – perfect for hot, sunny days

There’s no escaping it. It’s always hot in Malaysia. With fluctuations in temperature ranging from ‘hot’, ‘it’s really hot’ to ‘it’s crazy hot!’, there is no doubt that the temptation to walk around naked with the air conditioning on the coldest setting at full blast is a true test indeed. But few of us have the luxury of living alone, or the budget to keep the AC on every single second of every day. And if you don’t have an AC, walking around shirtless with the fan on super speed isn’t very good for the lungs either (or so they say). Short of soaking yourself in a tub full of ice, drinking water can help cool you down. And in hot, humid countries like ours, cold water is the way to go. But when you’re longing for something with a little more flavour, we’ve got a recipe for a refreshing watermelon lime mint cooler that’ll help quench your thirst and cool things down a bit. All you need is a decent blender, and the ingredients listed below, of course.

The breakdown

Watermelon is one of those fruits that helps you hydrate instantly, especially considering it’s actually 92% water! Perfect for those who don’t want to drink plain water because they think it tastes boring. Watermelon is also pretty low in calories, yet it contains a ton of vitamins including C, A, B1, B5 and B6. It’s great for your skin and hair, and can help improve digestion. And if you’re diabetic (or know someone who is) yet still have a sweet tooth you can’t deny, one of the amino acids contained in watermelon, when consumed and processed by your kidneys, turns into L-arginine, a supplement taken to help regulate glucose metabolism. Of course, if you are diabetic, you’ll want to skip the honey from the recipe.

Now, watermelon is known for being a ‘cool’ fruit, so if you’re one of those people who have a tendency to get chest colds easily, you may have been told to stay away from this fruit. Well, instead of skipping out on this yummy watermelon lime mint cooler altogether, we’ve added some ginger ice cubes which helps ‘warm’ this drink up internally while giving it a pleasant zing. If you’re not big on ginger in your juices, however, feel free to reduce the amount accordingly.

Mint leaves give this drink a nice, refreshing flavour and pairs so well with watermelon. And, did you know mint leaves contain more anti-oxidants compared to any other herb? It’s also great for your digestion, helps prevent memory loss and depression, aids weight loss and is great for oral hygiene. No wonder it’s a popular ingredient in toothpastes! However, be mindful not to go overboard though, as consuming too much mint leaves can lead to stomach irritation. Fascinating.

If you’re ready, let’s go make some cooler.


  • 500g frozen watermelon, cut into small cubes
  • 46g (5 cubes) frozen ginger juice (see below on how to make this)
  • 1 packed tbsp (about 3 stems) mint leaves + a few sprigs for decoration
  • 60g (6) calamansi lime
  • 75g (3 tbsp) honey
  • 320ml soda water

This recipe makes about 2 medium glasses.

Making ginger ice cubes

  1. Peel and blend ginger with water at a ratio of 1 part ginger to 3 parts water.
  2. Pour blended ginger through a strainer to remove any fibrous parts.
  3. Pour ginger liquid into ice cube trays and freeze overnight.

  1. Blend until smooth. If necessary, add a little bit of soda water to aid in the blending process.
  2. Pour blended watermelon into a couple large glass or a few smaller glasses and top up with equal amounts soda water.
  3. Decorate the top with a sprig of mint and enjoy your watermelon lime mint cooler while it’s still cold.

Extra tips

  1. It’s always a great idea to use a good quality blender for your smoothies so your ingredients don’t have to sit in your blender for too long and start melting and warming up from exposure to our lovely hot weather. However, not everyone can afford one of those blenders that can literally blend everything in seconds, so this is a good option if you’re shopping around for a new blender!
  2. Don’t freeze the watermelon whole! Instead, slice it up as you would if you were serving it regularly, removing the skin. You can choose to freeze the watermelon in slices and cut them later, or pre-cut them into cubes before storing and freezing in an airtight freezer-friendly container.
  3. Different brands of honey vary in sweetness. Adjust accordingly.
  4. If you’re impatient, you can skip freezing the watermelon overnight. However, your cooler won’t be as cold. At the very least, make sure it’s refrigerated and don’t let it sit in room temperature for too long before blending it up.
  5. Make extra ginger ice cubes and add it to other drinks for a little spicy kick! Orange juice with ginger ice cubes, anyone?


Now wasn’t that a thirst quenching watermelon lime mint cooler? And that ginger adds just the right amount of kick to get you going. The lovely pink tones and bubbly feel also makes this a great mocktail or party drink. But if you’re making the blended watermelon part beforehand, be sure to store it in a jug or jar with some cling film and keep it refrigerated. Add soda water just before serving your guests. Pretty paper party straws are optional.
