What Is A Rhubarb Slush?
It’s a super refreshing summer drink that combines tart fresh rhubarb with sweet pink lemonade, strawberry jello, and lemon-lime soda. Once combined, you freeze it and then serve it as a cold slushy drink.
Why You Should Make Easy Rhubarb Slush!
What I love about this drink is that you can make it with vodka for a fun summer cocktail or leave it out for a refreshing mocktail.
The jello in this recipe gives the slush a really great texture. It adds flavor but the gelatin also gives the slushy some body so it’s not watery. It’s like a cross between jello and a popsicle but served in a glass so you can scoop it up or slurp it up with a straw.
If you want a fun summer cocktail or mocktail for parties, this rhubarb slush is a great one! It’s such a fun drink and is so good on a hot summer day.

How to Make Rhubarb Slush with Vodka
Make the rhubarb juice: Place the rhubarb in a large saucepan. Pour the water in the pan and bring it to a boil. Simmer the rhubarb until it’s softened. Strain the liquid into a large bowl.
Mix: Add the sugar, lemon juice, jello mix, lemonade concentrate, and vodka if using it. Stir to combine.
Freeze: Cover the bowl and freeze the mixture overnight.
Serve! Stir to break up the frozen slush and scoop it into glasses or cups. Top it with lemon lime soda to add some fizz.
What does it taste like?
This slush drink is tangy, sweet, and a little sour! Rhubarb is very sour when it’s raw, but cooking it first and using the juice dampens that sour flavor. The sugar balances it out even more and the lemonade adds a sweet tartness.
This combination makes this icy cold slushy so delicious and refreshing!
How long does rhubarb slush keep?
Frozen rhubarb slush will keep in the freezer for several months! For the best results, store it in an airtight container in the coldest part of the freezer.
Variations
A classic rhubarb slush is made with rhubarb, lemonade, strawberry jello, and lemon-lime soda but I have some ideas if you want to switch it up!
- You can make it with or without alcohol!
- If you make it with alcohol, try swapping the vodka for white rum.
- Instead of lemon-lime soda try ginger ale or ginger beer.
- Any fruity jello mix will work, too!

You are going to love this rhubarb slush – make it for all your summer parties, pool days, and BBQs and it will be a hit! It’s so refreshing – a perfect summer treat. Enjoy!

Question: I canned rhubarb juice concentrate (supposed to mix 1/2 with 1/2 water, then add booze and 7-up or whatever. Any estimates on how much volume the rhubarb in this recipe is? Before adding the other ingredients? TIAz…looks great!
