Rhubarb Cosmopolitans

Alice Seuffert


The rhubarb — bright red with speckles of green — glistened on my kitchen counter. This spring veggie is a welcome gift after winter, popping up in our gardens and in our local farmer’s markets.  While its beautifully tart flavor is usually paired with strawberries and reserved for pies, I thought it best be made into a martini.

Since rhubarb is a celebratory recognition of spring, I thought it would be perfect in everyone’s favorite celebration martini, the Cosmopolitan. The tartness of the rhubarb would be an easy substitution for cranberry juice, and the brilliant red color would make it a perfectly pink cocktail.

The open windows welcomed in a spring breeze.  My sister studied nearby; it was rare that we sat together in quiet.  The kids napped and life was slow on this Saturday afternoon. My sister looked up from her book and said, “Remember when we used to eat rhubarb right out of grandpa’s garden?”

I did, the huge stalks still covered in dirt and sour-patch kids tart. I laughed thinking about my little rhubarb plant in my own backyard, its sad tiny shape with stir-stick sized stems. It made me wonder how long that rhubarb plant at my grandpa’s house had grown. It had probably welcomed many springs over the years in that spot near the steps.  A bush more than a plant, it grew without any care or attention, surrounded by weeds, my grandpa’s rhubarb had thick stems as long as his forearms.


While I made the rhubarb syrup, I sat anxiously watching it drip. It made me think about the excitement and anticipation during summer when I’m canning jam. The sweet smell of summer fruit fills the air, the stove top sticky with red berry-stains, and the sound of canning jars popping on the kitchen counter. In no time, the tart spring veggie transformed into a bright, sweet pink syrup.

Without hesitation, I dipped my finger into the syrup with flecks of vanilla bean—it was sweet and decadent. I shook it with vodka, triple sec, and lime juice—it was the exactly the celebration cocktail I envisioned: the rhubarb syrup gave the drink a subtle tartness, and it was worthy of a slow sip to savor the fusion with the alcohol.

Rhubarb Cosmopolitans

Rhubarb Syrup

  • 3 cups chopped rhubarb
  • 1 cup water
  • 1 cup granulated sugar
  • 1 teaspoon vanilla bean paste or extract

Rhubarb Cosmopolitans 

  • 1 cup ice
  • ½ cup vodka
  • 1/3 cup triple sec
  • 3 tablespoons rhubarb syrup
  • 1 teaspoon lime juice
  • lemon for lemon twists


In a saucepan over medium heat, bring rhubarb, water, sugar, and vanilla to a boil. Cook 15-20 minutes until rhubarb is completely cooked and soft.

Remove pan from heat and allow to cool.

Place a fine mesh strainer over a bowl (ensure fit so mixture and liquid does not leak out the sides) and place rhubarb mixture in the strainer. Allow juice to drain into bowl and lightly press mixture into strainer until syrup has completely drained. Once drained, you will should have 1 cup of rhubarb syrup. Reserve the cooked rhubarb for future use, see notes below. Chill rhubarb syrup until ready to use.

In a cocktail shaker combine ice, vodka, triple sec, rhubarb syrup, and lime juice. Shake profusely for 5 seconds and pour into two martini glasses. Garnish with lemon twist (use a knife or vegetable peeler to remove a long strip of peel and then twist) if desired.
