Rhubarb juice is a deliciously tart drink made from fresh or frozen rhubarb that can be used in numerous ways. This rhubarb juice recipe makes use of both the liquid and the cooked rhubarb to minimize waste and maximize rhubarb deliciousness, no juicer required!
WHY MAKE RHUBARB JUICE?
My love affair with rhubarb has been going on for some time now. I can date it to a dehydrator workshop over a decade ago, when dehydrating expert Mary Bell passed around samples of a homemade fruit leather she called rhubarb lace. I was blown away by the flavor and joined the rhubarb fan club right then and there.
Soon after, I got my hands on my very first rhubarb division, which I’ve now re-divided into 8 lovely rhubarb plants that thrive in our tiny 1/10 acre corner lot. The vast majority of rhubarb picked from these beloved plants have been turned into the rhubarb leather I adapted from Mary Bell’s original recipe. Some has also become rhubarb crisp or rhubarb sauce or gone into some of the other delicious uses for rhubarb, but most of it heads to the dehydrator to become beautiful rounds of tart-sweet rhubarb leather.
You can get my recipe for homemade fruit leather made from rhubarb and taste for yourself what all the fuss is about.
But rhubarb juice, that was something I didn’t fully appreciate for many years. I would cook up huge pots of rhubarb for leather-making, and the leftover cooking liquid mostly got poured down the drain.
It was a gorgeous pink color but very tart, so as someone determined to avoid wasting anything in the kitchen (see these root to stem recipes for proof!) I started to wonder what else could be done with it.
I love refreshing tart drinks on hot days, so I started saving a little of my rhubarb juice to add to my homemade seltzer. Rhubarb spritzer turns out to be a delicious thirst-quenching drink!
(If you’re still buying bottles or cans of fizzy water, I beg you to stop. One of these easy-to-use little home soda makers will save you so much money and keep so much plastic out of the waste stream. Here’s more on why and how to go zero waste.)
But try as I might, I couldn’t drink enough sparkling rhubarb soda to warrant keeping the many quarts of juice leftover from a big batch of rhubarb leather.
But when my 6-year-old decided she wanted to try running a lemonade stand right after we’d made fruit leather, I gave her a few quarts of rhubarb juice to add to her lemonade as a second option.
The sign she made before she opened her stand suggested she, too, underestimated the value of rhubarb juice:
I eventually persuaded her to price the rhubarb-added drink the same as plain lemonade, and she begrudgingly made a new sign.
Much to her surprise, most folks stopping at her stand for a cool drink opted for the rhubarb lemonade, even without a discount!
She considered upping the price of the pretty pink rhubarb lemonade when customer after customer asked for it.
Live and learn 🙂
TWO RHUBARB RECIPES FOR THE PRICE OF ONE
I love that rhubarb juice is basically a freebie you get when you’re making something else. Who doesn’t like free, right?
Most recipes for rhubarb juice have you strain and throw away the rhubarb, but this boggles my mind. Why on earth would you want to waste all that yummy food??
This rhubarb juice recipe makes TWO delicious rhubarb concoctions, rhubarb leather or sauce AND rhubarb juice. Two for the price of one!
(Except you can totally get your rhubarb for free. Even if you’re not growing it, there’s very likely someone nearby who hasn’t realized how awesome the rhubarb growing in their garden is. When someone on one of my neighborhood lists asks if anyone has some, they always get numerous offers of rhubarb.)
If you don’t want to make rhubarb fruit leather, you can make a simple rhubarb compote or rhubarb sauce, but do make use of that yummy rhubarb!
IS RHUBARB JUICE GOOD FOR YOU?
Like hibiscus tea, this sour drink can be rough on your teeth, so if you plan to drink a lot of it, use a straw and rinse well with water afterward.
Also, it’s important to understand that rhubarb leaves contain toxic amounts of oxalates and we don’t eat them. Stick to the stalks only, and be sure leaves are completely removed before making rhubarb juice or other recipes.
IS RHUBARB JUICE PALEO?
Yep, since rhubarb juice is nothing more than a vegetable and some water, it’s very much paleo. If you make a rhubarb drink that needs sweetener, just be sure to pick your favorite paleo-friendly sweetener.
But do try a splash in plain seltzer before sweetening. It’s really fantastic on its own!
CAN YOU USE FROZEN RHUBARB?
Yes, frozen rhubarb can work for making rhubarb juice. When you defrost your rhubarb, much of the liquid will release on its own. The defrosted rhubarb will take up less space in the pot, so you’ll naturally add less water.
Juice from frozen rhubarb may be a little more concentrated than when made with fresh rhubarb. The color may also be deeper, but the taste is pretty much the same. Since you’re diluting it to taste anyway, it doesn’t matter much how concentrated it is.
Here’s what you need to know about how to freeze rhubarb.
WHAT TO DO WITH RHUBARB JUICE
First off, don’t drink this stuff straight. It’s SOOOOOO tart! If you really like tart drinks, you could dilute your rhubarb juice with water, but unsweetened rhubarb drinks aren’t for everyone. Add a little stevia or honey, serve over ice, and this simple rhubarb drink could work.
A splash of rhubarb juice in seltzer, however, is an entirely different thing. This sparkling and beautiful homemade soda is delicious and refreshing even without added sweetener. Add a little or a lot, according to your taste.
You can make loads more rhubarb drinks by using this rhubarb juice as a mixer. Try it with seltzer and vodka as a cocktail, or add a splash to your favorite iced tea. I haven’t tried, but I bet it would be amazing in a margarita or daiquiri.
Or put some rhubarb juice in lemonade and your lemonade stand will be the most popular in town!
Freeze any leftovers from your lemonade stand in popsicle molds, and you’ll have easy rhubarb lemonade pops. Yum!
