Fresh Watermelon Mojito with Homemade Watermelon Syrup

I love summer. And watermelon. And mojitos. But mostly mojitos. If you visit Pink Recipe Box often, you’ll know that I love making seasonal drink recipes and this fresh watermelon mojito is one of my latest summer cocktails. Mint, lime, watermelon and white rum – what’s not to love? We went out last night for a few drinks – on a school night, I know! A few turned into many and I’m more than a little tender this morning. But since this cocktail recipe is so delicious, I just couldn’t hold off on sharing this drink with you any longer!

Chilling on the balcony whilst soaking up the sun with a cocktail in one hand and my Kindle in the other is one of my favourite ways to spend an afternoon (and my life, actually) and this easy watermelon mojito recipe fits in perfectly. It’s rather sweet – something which is a must for me when it comes to cocktails – and is just so…drinkable! Plus, just look at that colour. It is the perfect peachy pink colour that I did not expect to get at all. The pink of the fresh watermelon simple syrup works so beautifully with the green of the mint and the lime it’s unreal. It’s like the perfectly paired outfit in cocktail form!

The base of this cocktail is – as I’m sure you can guess – the homemade watermelon syrup, which is oh-so  good and easy to make! I originally set out to make this cocktail but I just couldn’t manage to get the juice out of my watermelon. It might have had something to do with the fact that I was essentially trying to smush a watermelon through a sieve, but there you go. Instead, I decided to make a watermelon syrup and stir it in with classic mojito ingredients – and I was so glad I did! You don’t have to use the syrup solely for this mojito – you could mix it with soda water or lemonade for a child-friendly summer drink so the little ones don’t feel left out.
