We’ve been making watermelon smoothies forever. In fact, the very first recipe in the “Drinks” category was the watermelon smoothie. It was updated in September 2010 when my daughter, Sam, made a picture pretty pitcher of her version. It was after that September 2010 update when reader RQ posted the following comment:
She’s so right about the lime juice. It worked wonders.
But why, you might ask, add something sour if what one wants is a sweet drink? For some strange reason, adding a little sourness makes something sweet taste sweeter. It’s the contrast, I suppose. Instead of something that can be cloyingly sweet, one gets a nice balance that makes the flavors more appealing. It’s for the same reason that one adds a pinch or two of salt to cake batter. As RQ said, it’s all about the balance. »
