Love ’em or hate ’em?

I, for one, love it. As a child, I couldn’t get enough of sour treats, and the more tart, the better. There was something inherently fun in eating something so bold in flavor that it would elicit a face scrunching, eye tearing expression. It sounds masochistic, but I know I’m not the only one. I find that people who love kumquats, those little nuggets of sweet and sour, have a similar penchant for tartness.

Mouth puckering delights are still a favorite, but I also like to temper the flavors and balance it with sweetness. If you’ve never tried kumquats before, I have the perfect way for you to ease in to it. Sweet and tangy, I think you’ll really love this Kumquat Lemongrass Rum Cocktail.

Think of it as lemonade for grownups. If you’re a kumquat doubter, I know you’ll be convinced.

How to Make a Kumquat Cocktail

First, prepare the Kumquat-Lemongrass Syrup. Chop two stalks of lemongrass into 2″ pieces. Use a mortar and pestle to help release the juice. Combine the pieces of lemongrass with water and sugar in a small saucepan. Squeeze halved kumquats into the saucepan and drop in the pressed fruit too.

Bring the syrup to a boil then lower the heat and simmer for 30 minutes. Allow to cool in the refrigerator and then strain.

After the syrup has been strained, it’s ready for cocktail creation. In a mixing glass, combine rum, kumquat-lemongrass syrup, fresh kumquat juice, and ice. Shake and serve over the rocks. Garnish with a kumquat half. That’s it!

    Love kumquat’s. I have a friend whose neighbor has a tree and I am so jealous. I would eat everything right off the tree. Like you sour candies are my favorite. I would eat sour skittles until the roof of my mouth hurt. Now that is masochistic. This drink sounds amazing! Pinned.
