Watermelon Margaritas

by Lori on July 7, 2010

I can guarantee these margaritas will be a regularly featured cocktail at my house this summer.  They are so refreshing, tasty and light.  Perfect for a warm afternoon.  And here’s the kicker: they’re only 105 calories each, or so it says in the July 2010 issue of Cooking Light magazine.  I beg to differ.  I think it’s less.

Let’s discuss.

You see, about a month ago when I started working out with a trainer, she turned me on to a free app for my iTouch called Lose It.  I type in everything I eat and drink throughout the day, and the app gives me data to keep me in the proper zone for effective metabolism.  When I plugged in all the specifics for this margarita and divided it by the recommended number of servings, I came up with 86 calories. 

I believe everything my Lose It app tells me.  It’s in charge of my eating and drinking life these days.

So download this app and make yourself a double, on the rocks!  After this past 4th of July weekend, I bet you’ve got everything you need to whip up a batch of these.

Watermelon Margaritas
adapted from Cooking Light, July 2010

2 teaspoons sugar
1 lime wedge
3 1/2 cups cubed, seeded watermelon
1/2 cup (4 ounces) tequila blanco (silver label)
1 tablespoon ultra fine sugar
3 tablespoons fresh lime juice
1 tablespoon Grand Marnier
Lime wedges or watermelon balls for garnish (optional)

Place 2 teaspoons sugar on a saucer.  Rub the rims of 6 small glasses with 1 lime wedge; spin rim of each glass in sugar and set aside. 

Place watermelon in a blender and process until smooth.  Pour pureed watermelon into a fine meshed strainer and using a rubber spatula, press the juice out into a pitcher.  Discard pulp and small white seeds.  Add tequila, sugar, lime juice and Grand Marnier to pitcher and mix.

Fill each prepared glass with 1/2 cup crushed ice.  Garnish with lime wedges or melon balls, if desired.


The next time I make these, I will omit the sugared rim.  With watermelon being so sweet, and the added sugar into the mixture, you really do not need the sugared rim in my opinion.  The caloric contribution of the sugared rim is not included in the overall calories per serving; it may be a couple of calories at the most.

The original recipe called for 2 tablespoons of sugar to be added into the mixture.  I started with 1 tablespoon to taste.  I didn’t need to go any further.  If your watermelon isn’t very sweet, you may want to increase the amount of sugar (15 calories per teaspoon, if you’re counting).

Ultra fine sugar is also referred to as baker’s sugar and easily obtained in most supermarkets.

I recommend chilling the margarita mixture prior to serving over ice.

Calories per serving calculated from the Lose It app and Grand Marnier website:
Tequila: 43 calories
Watermelon: 26.5 calories
Sugar: 7.5 calories
Lime juice: 2.5 calories
Grand Marnier: 6.3 calories
Total: 85.8 calories per single serving, 172 calories for a double serving
