At the first sighting of fresh rhubarb every spring I make up a batch of my sweet/tangy Rhubarb Butter ~ spread it on toast, muffins, biscuits, or just eat it by the spoonful!
I’m madly trying to get the most out of the short rhubarb season. The other day when I asked my produce guy for some he went in the back and brought me out a HUGE armload of stalks. We’re leaving town this week so I need to preserve it for later. And I’ve always loved old fashioned fresh fruit butters, I love the smooth, silky texture, and I love the way the flavor is intensified. They don’t require sugar like traditional jams, and so the essence of the fruit comes through stronger. The only reason I used a little sugar in this recipe is that rhubarb is super tart. You can do this with lots of different fruit, from apples to peaches and plums. Berries too, but you’ll want to strain out the seeds. I have an incredibly silky CRANBERRY BUTTER recipe that you can make in the slow cooker.
With no pectin, and very little, if any, sugar, this is an easy way to preserve fruit. You can blend varieties, or just stick to one. You can add spice or flavoring, too. I added cardamom to my rhubarb, but next time I’m going to use a vanilla bean.
Ingredients
- 1 lb rhubarb
- 1/2 cup sugar
- squeeze of fresh lemon
- optional: 1/4 tsp cardamom, or cinnamon, or the seeds of 1 vanilla bean
Instructions
- Rinse the rhubarb and trim the ends Slice it into 1 inch pieces and put in a heavy bottomed pot along with the sugar. Add 2 tablespoons of water and the lemon juice, and stir to combine.
- Heat, stirring constantly, until the rhubarb starts to give off juice and the mixture comes to a boil. Boil gently for about 20-30 minutes, until the rhubarb is very soft and mostly broken down.
- Puree the mixture, in batches if necessary,. Be careful when pureeing hot liquids, as they can 'explode' up through the spout of the processor or blender.
- Put the puree in a clean pan back on the stove and bring to a boil, then turn down the heat and let it gently bubble away until reduced and thickened about another 20 minutes, Stir often, and be careful not to let the fruit scorch. If you are using the spice or vanilla bean, stir it in now.
- Spoon the finished butter into a glass jar. Let cool, then cap and refrigerate. It will thicken further as it cools. You will have about a cup.
Notes:
- If you want to make a larger batch, you can freeze this, and you can also can it. I just keep it in the fridge, it will be scarfed up within a couple of weeks.
- There is no firm rule about how long to cook the pureed fruit. The longer you cook it and reduce it down, the thicker it will be. It’s a matter of personal taste.

August 11, 2017 at 8:20 amThose are Weck canning jars, Robyn, and they come in all shapes and sizes. It’s a German company ~ here’s a link to them on Amazon:https://www.amazon.com/gp/search/ref=as_li_qf_sp_sr_il_tl?ie=UTF8&tag=thvifrthgris-20&keywords=weck jars&index=aps&camp=1789&creative=9325&linkCode=xm2&linkId=92e67a7fb5aa49baad700eba3d1030f6

May 17, 2017 at 5:03 pmI am wondering if this could be made (step #2) in a crock pot? Any thoughts?? Thanks!

May 17, 2017 at 5:25 pmHi Marcy ~ yes, I’ve made several fruit butters in the crock pot, my Cranberry Butter is one, here’s the recipe for reference: http://theviewfromgreatisland.com/minimal-monday-crock-pot-cranberry-butter/ You might want to add a touch of water if you’re going to leave it in the crock pot for a long period.

February 23, 2017 at 8:15 pmHave you ever tried adding strawberries to this. I’m just wondering how it would come out or how much to add. I was thinking 2 parts rhubarb one part strawberry but I haven’t made fruit butter before so I wasn’t sure how this would change the texture.
Sue
February 23, 2017 at 9:14 pmI don’t think you can go wrong, Megan, because I’ve made all kinds of fruit butters…I say go for it, either in a 2 to 1 or even 1 to 1 ratio!

August 10, 2016 at 3:46 pmCould I use honey instead of the sugar?
Sue
August 10, 2016 at 4:03 pmI think that should work, Christina — let us know your results!

May 11, 2016 at 6:20 pmUnbelievably good. Like this way better than Rhubarb Jam. Used Vanilla in mine. Waiting on the toaster for a second helping. Thank you!

May 11, 2016 at 6:24 pmI’m so glad you like it Stephanie, I agree, fruit butters are much better than jam :)

March 14, 2016 at 6:46 pmI’m wondering if you can use frozen rhubarb & if so how much would a pound be in cups? Also wondering about using the crockpot instead of stove for final cooking? It would be so much less likely to scorch. I need to use up my freezer rhubarb before the fresh starts soon.

July 20, 2015 at 5:49 pmAny tips for canning it? It sounds divine, and my rhubarb patch still has some life left!
Sue
July 20, 2015 at 6:05 pmI’m so sorry, I’m not much of a canner, Kayleigh!

June 4, 2014 at 11:05 amThis will never make the freezer. I could eat it with a spoon. I added a wee bit more sugar in the second “cooking” process as mine was a bit too tart. Mine is cooling and I added a vanilla bean. I’m taking it with homemade cream scones to my friends house tomorrow. YUM and thank you!!!

Love the color.
I especially like the styling of your lead photo.
The Kerr mason jar, the coffee cup and the vintage knife bring such old home memories to mind.
Delightful.

June 2, 2014 at 3:06 pmThis butter sounds amazing! I bet it would be excellent as a quick filling for a lemony cake…or maybe almond? Or both! :)

June 2, 2014 at 2:09 pmPerfect timing!
I cut massive amounts of Rhubarb out of my garden last night and this sounds wonderful :)
I’ll freeze some and especially enjoy it during the -35 C snowy winter, a reminder that spring will come again just when I’ll need it the most!
Too bad you didn’t live here, I always have tons of Rhubarb and can’t seem to give it away unless it is in the form of Rhubarb Coffee Cake :)
Sue
June 2, 2014 at 2:24 pmOh I would LOVE to get some neighborly rhubarb!
Lynne
June 2, 2014 at 4:09 pmHi Sue,
I just made the Rhubarb Vanilla Butter (used 3 lbs of rhubarb & still have a lot left in my yard) and it is absolutely amazing!
It reminds me of the stewed rhubarb my grandmother made, I ate copious amounts of it on toast and also on ice cream when I was little.
I could never quite duplicate the flavour of hers and this is as close as I’ve ever gotten. Heaven on a spoon :) Thank you!

June 2, 2014 at 9:52 amThis is wonderful – I recently made Kumquat marmalade and thought it was way too sweet. I didn’t even post it on the blog. It was pretty but I would have preferred rhubarb butter! Love the color and I know it is tasty. Have a great trip!
