This Rhubarb Bourbon Sour Cocktail recipe with a honey rhubarb simple syrup is a refreshing and seasonal take on the classic drink.
I thought about just designating April "Rhubarb Month," because in all honesty, it's about the only thing that has consistently graced the shelves of the fridge in the last few weeks.
So after covering breakfast with these cinnamon rhubarb muffins, I then switched gears and went straight to cocktail hour.
Honey-sweetened rhubarb bourbon sour cocktail it is.

Ingredients for a Rhubarb Bourbon Sour
I can't get enough of using seasonal fruit and turning it into a quick simple syrup. For this rhubarb bourbon sour cocktail, I made the simple syrup with honey, which goes wonderfully with rhubarb's tart earthiness.
Here are the ingredients you will need:
- Fresh rhubarb
- Honey
- Lemon juice
- Bourbon

Making Rhubarb Simple Syrup
A quick simmer until the honey melts and the rhubarb starts to break down, then strain, and you've got a beautiful pink simple syrup.

A drink for bourbon lovers
Once your rhubarb simple syrup is ready, the cocktail comes together in no time. As bourbon lovers over here, adding this drink to our repertoire has been a refreshing change.
The tart rhubarb with the honey-sweet and the lemon-sour work together in all the right ways.

How long will the sour mix keep in the refrigerator?

Hi Candace - the simple syrup should keep for up to two weeks in the refrigerator. Cheers!

Ha, that's me and asparagus + strawberries right now. For some reason rhubarb hasn't made an appearance yet in my CSA basket! This looks spectacular.
Tessa
Funny how we get in these cycles! Dinner has been seriously lacking at our place. ;) Thanks, Jennifer!

This is 100% my kind of drink. I also love to create seasonal simple syrups with fresh fruit, and then my husband yells at me because I fill up half the fridge with jars of simple syrups ... oh well. This one sounds so good! I love the use of honey in it, too.
Tessa
Hahaha, yes, we have multiple bottles of syrups as well! xo

I'm still dying to get my hands on some rhubarb Tessa! I've checked three local stores and nothing. This cocktail sounds delicious. I'll keep searching! Happy weekend!
Tessa
I can feel it - you are going to find some so soon! :) Happy weekend to you, my friend!

Drive around your neighbourhood and look for someone with un-harvested rhubarb in their yard, and go knock on their door and ask for some! Then, take double the amount you need, double your recipe, and bring them back some delicious syrup made from their own garden! So many people have rhubarb that needs tending! What starts as asking for a favour, turns into a neighbourly gift!
