Watermelon: from agua fresca to margarita

Watermelon: from agua fresca to margarita | casaveneracion.com

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.

Watermelon Agua Fresca

Yesterday, reeling from the heat and humidity, I made a pitcher of watermelon agua fresca (read more about agua fresca). Not with grenadine, however, but with simple syrup infused with lemon zest, and some lemon juice.

After Speedy and I had consumed two glasses each of the watermelon agua fresca, there was still some left and I made that into watermelon margarita. Both recipes are below.
