    No one has ever turned down my ruby red grapefruit cosmo cocktail. No one! Why? Because the full body of the grapefruit juice combines so nicely with the premium alcohol.

    I’ve made these cosmos two different ways. I’ve made them with freshly squeezed grapefruit juice and I’ve made them with store bought juice. Which do I prefer? You may be surprised but I’m going to say store bought.

    I know, I know. I’m usually into freshly squeezed, but when I usually serve this ruby red grapefruit cosmo, it is at a dinner party and I want to enjoy my party and I don’t want to be manually squeezing grapefruits all evening. Not only is it time consuming, but it’s costly.

    Helpful tips

    • If you are going to squeeze your own, make sure you use ruby red grapefruit
    • Slice the garnish different ways, experiment with a grapefruit wheel, a wedge or a chunk.  You can also use two wheels as that makes for a pretty drink
    • If you can’t afford premium ingredients, it’s okay to use mid-level as with the robust flavor of the grapefruit, you won’t notice the difference as much
    • Shake vigorously so the ice breaks off in slivers.  There is nothing like little ice chips floating in your drink

    If you want to save some money and make your own orange liqueur, my friend Laura has an awesome recipe.

    How to make a ruby red grapefruit cosmo

    It’s super easy, there are only three ingredients!

    Fill cocktail shaker halfway with ice. Get a measuring glass and two martini glasses.

    After measuring, pour each ingredient in the shaker.

    Step one

    Gather the ingredients – vodka, orange liqueur, ruby red grapefruit juice.

    Step two

    Measure 4 ounces vodka.

    Step four

    Step five

    Cut a thin grapefruit wheel and cut off the rind and cut the rind in half.  Cut a chunk of grapefruit, remove the rind and throw it away.

    Step six

    Cap the shaker and shake it for 30 seconds.

    Step seven

    Strain the grapefruit cosmo between the two glasses.  Twist both halves of the rind and place one in each glass.  Add the grapefruit wheel to the bigger glass and the chunk of grapefruit to the other.

        Yay. I love it and so don’t my guests :). Remember, if the drink isn’t sweet enough for your taste, you can add some simple syrup. Let me know how they came out!

        Kara, I got both of the glasses from Crate and Barrel. The one with the big base is more expensive than the other! I love them both and actually have another martini glass from C & B that I have that I use a lot!

        For this one, I would do a sugar rim, but I usually don’t garnish the rim. But I know people have used colored sugar before. Thanks for your question Kelly! Cheers.
