Watermelon slush recipe

Make the coolest, easiest, summer watermelon slush that everyone loves and enjoys. Make this watermelon slushie on the hottest days and enjoy every sip.
Every summer I love to lug a 20 kg watermelon home. It is kind of a more satisfying feeling than pumpkins at Halloween. This year too to match up the Malaysian heat, we have lined up a giant watermelon.
When we get home, the first couple of days are all about watermelon slices and watermelon sherbet. Slowly, the liking intensity vanes and we look for new ideas like smoothie and curry. Finally, we have reached only halfway through it!
By then, all of us have had our watermelon fill. This is when we start freezing the cubes and then blending them as slashes. Since the process allows us a couple of weeks’ gap from the watermelon repertoire,  we enjoy the cold slush more.

What is a slush?

Slush or slushie is a cold beverage made with shaved ice and a flavoured drink. The word originates from the similarity of this drink to melting snow which will be slooshy. Here is the fun science part, slush behaves like a non-Newtonian fluid, a kind of solid that turns fluid upon pressure acting on it (check this post to know more).
There are two ways of making a slushie, shaving the ice and poring the flavour drink over it is one way. The other is to chill the flavouring drink and blend it up to fill a cup. The second method is what we have used to make this watermelon slush.

Ingredients to make slush

Watermelon: Choose a fresh watermelon. look for the field spots and the wideness of the stripes. Even better is picking up a seedless one as then you don’t have to dig the seeds out.
Lemon: the tartness from the lemon brings the best flavour of the watermelon and makes it feel sweeter.

Let’s make slushie:

The predominant fact of making this watermelon slushie is that we are not using any ice, but rather freezing the watermelon itself. So peel and cube the watermelon flesh and freeze first before proceeding to blend. Blend the frozen cubes til the ice breaks down and forms a smooth mix. Squeeze in a bit of lemon juice and mix well. Serve the slush immediately.


The basic watermelon slush is like a blank canvas. Depending on the herbs and berries you have you can make a few different versions. You can also upgrade this to an grown up summer party version with some alcohol in it.
Herbs: the choisiest combination with watermelon is fresh mint leaves. This brings a lot of freshness to the recipe. However, of later I am fond of the rosemary-infused ones as they are a bit more subtle.
Berries: instead of just having watermelon try a handful of frozen berries of your choice added to it. The slight tartness of the berries brings the sweetness of watermelon to life. You can have just raspberries, strawberries or mulberries added to it or a mix of berries.
Alcoholic: this is not a regular version and though not a huge favourite of mine, was asked by my readers. Vodka is the best to combine with watermelon.

What to do with all that watermelon peel?

The watermelon rind and peel are equally edible. You could use the white part to replace cucumbers in salads or ashgourd in curries like aviyal and porichakozhambu. We love to make a watermelon we light and easy watermelon rind sabji. If possible we add the white part to smoothies and neer moor too. The peel being a bit thicker,  is better to be used cooked. We grind it to make a fantastic thogayal. Again, if you cube and cook the peel and freeze you can use it in curries later.
