One small seedless watermelon, chunked. Juice of one lime. A handful of fresh mint leaves. Rum to taste. All of it blended until smooth. Served over ice cubes. Garnished with extra mint.
The mint blends into the watermelon and turns the drink a slightly deeper pink. The lime is sharp underneath the sweet melon. The rum is there for warmth, not strength. This is a cocktail that tastes like a pool day and takes less time to make than to drink.
Tips for Making Watermelon Cocktail
Blend the watermelon until smooth
Remove any seeds if using a seeded watermelon. Blend the chunks with lime juice and mint until there are no pieces left.
The drink should pour like juice, not like a smoothie. If it is too thick, add a small amount of water.
Add rum to taste
Start with one ounce per glass and adjust. The watermelon is sweet and masks the alcohol quickly, so pour carefully.
Dark or spiced rum changes the flavour. A white rum lets the watermelon come through cleanest.

Frequently Asked Questions
Can I make this without alcohol?

Can I make a pitcher?

Can I use frozen watermelon?
Yes. Frozen chunks make the drink slushy without ice. Blend from frozen and skip the ice cubes.
