Ingredients and substitutions
Here are a few quick notes about the ingredients in this recipe. You can see a complete list of ingredients and instructions in the recipe card below.
I can't get enough of using seasonal fresh fruit and herbs (like mint leaves) and turning it into a quick simple syrup.
For this rhubarb cocktail, I made the simple syrup with honey (like in my rosemary syrup), which goes wonderfully with the tart earthiness of the spring veggie.
Fresh rhubarb - Once cooked, the stalks have a delicious tart flavor.
Honey - Making a simple syrup with honey instead of cane sugar compliments the flavors of the cooked stalks.
Lemon juice - This is what gives this drink its sour taste. Fresh lemon juice is best. It plays well with the tart veggie and sweet honey.
Bourbon - Use your favorite bourbon!
Before you start: Get out all of the ingredients.
Step 1: Add water, honey, and chopped stalks to a medium saucepan. Heat gently until the honey dissolves and the chopped pieces start to break down.
Step 2: Let this cool to steep. Strain liquid through a fine mesh strainer and store in the fridge.
Step 3: Add cocktail ingredients to a shaker and go to town!
Step 4: Place ice cubes in a cocktail glass and garnish with some extra stalks if desired.
- Mash the syrup mixture just enough so the flavors of the "rhubarb juice" will come out. We aren't pureeing it or using the pulp, so don't worry about smashing too hard. This will give our syrup and drink that gorgeous color.
- Use extra crisp stalks of raw rhubarb or make a ribbon as a garnish. You can also add a lemon wheel.
- Store the extra simple syrup in an airtight, sealable container in the refrigerator.
No special equipment is necessary, but I highly recommend picking up a cocktail shaker for your home bar. They are inexpensive and help to chill the drink with ice as well as strain any ingredients for a really clean drink. Other helpful equipment to have on hand includes a silicone ice cube tray and a jigger for measuring.
Definitely! Especially if you have frozen your own from the garden, go right ahead and drop it right into the saucepan. You don't have to thaw first, it will just take slightly longer to heat up and reduce.
Yes! When it is in season, you can find rhubarb in most grocery stores. Your local farmers market is another great place to find it. When it is not in season, buying frozen is an easy way to have it year-round.

Hi Jacqueleena! Thanks so much for catching that. It was calculating the rhubarb simple syrup recipe in addition to the cocktail. It has been fixed! Thanks!
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.
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.
Hahaha, yes, we have multiple bottles of syrups as well! xo
all about all the rhubarb. these rhubarb sours are calling my name!!
Thanks, Alana! You can never have too much. :)

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!
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!
