Watermelon smoothies sum up summer to me. It’s bright pink, and bright tasting, but not super sweet – and ultra refreshing. It’s is a great option for a watermelon that’s sweet but not really crisp. I love watermelon but don’t grow it myself – it’s tricky without a greenhouse – and my luck is about 50/50 with buying good ones.
Watermelon is about 92% water, but boasts a whole host of beneficial nutrients inside that green shell. It’s high in vitamins A, B6, and C (awesome for healthy skin and hair), lycopene, antioxidants, and amino acids. This smoothie also features strawberries, raspberries, and a bit of lemon.
This little melon has some of the highest lycopene levels of any fresh produce. Lycopene is linked to a healthy heart and bones, and can help prevent some types of cancer and cardiovascular disease. Just keep in mind that if you eat a whole watermelon in a day, your body might overload on lycopene and make you sick. I know I’ve done it.
Ingredient Notes and Substitutions
- Berries: go for more strawberries or raspberries as you prefer, changing up the ratio to what you have on hand or your preference.
- Sweetener: as usual, I use honey and maple syrup interchangeably, but if you’re not vegan, I recommend honey for the flavour here. You really don’t need to add any if the melon is sweet.
- Limes: lemons and limes are equally good, though lime is maybe a bit more familiar in flavour. I can’t get limes as easily as lemons where I live, so I usually go with lemons now.
If the juice warms up after sitting out for a little while – if you’ve served it in a pitcher, for example – don’t be tempted to add ice. It won’t taste good. Either add frozen berries or watermelon squares, or refrigerate it again until chilled.
As I mention above, this is a good way to use a slightly soft or less sweet melon that you may not love on its own. A bad melon will mean a bad drink, but a just not-quite-right melon will be perfectly good with berries and a bit of honey in the mix.
It’s been harder for me to get frozen strawberries lately, so for the smoothie pictured I used mostly frozen raspberries and then some strawberries from my garden. You can use any variation on the ratio of strawberries to raspberries you like here.
How to Store
Storage: this keeps surprisingly well for a day or two in the refrigerator. If it’s in a pitcher, just cover with a plate or waxed wrap and give it a stir before serving.
Freezing: I think it would make for very nice popsicles, and you could freeze and then blend for a kind of slush.
- For blender trouble: if you just have an immersion blender, like me, you may have a bit of a time getting the strawberries to blend fully. If I’m having difficulty with this, I let the strawberries mostly thaw but make sure the watermelon is chilled before starting.
- Sweeten to taste: the sweetener is optional, and the amount you use will depend entirely on how sweet the fruit is.
