Sugar Free Strawberry Rhubarb Sauce Recipe

Sugarless and Sweet Strawberry Rhubarb Sauce

Rhubarb is on the return – at least for this harvesting season!

I harvested a large stash of rhubarb the other day  – and I did not even touch my second garden patch of rhubarb. There is still much more to come.

And as with every year, I pick my rhubarb and then ask myself,

What am I going to do with all of this rhubarb?

Freshly Picked Rhubarb
Yes, this is my freshly picked rhubarb stash – first one of the season – more to come!

Even though I ask myself that question every year, every year my first answer is the same – I will make some rhubarb sauce. It is quick and easy to make and will easily consume a whole lot of rhubarb in one go.

I remember as a kid when my mother would make rhubarb sauce. I would lather that stuff on some toast and butter…yummy. I would also take a stick of rhubarb and dip it into a bowl of white sugar as a snack. Without the sugar…not so much.

Back in those days, we weren’t so concerned with sugar consumption – mostly, I guess, because we really did not consume that much sugar on a daily basis – unlike today. Making rhubarb sauce back then would always include sugar.

Today, me and my family are trying to cut down on refined sugars. And now that I ‘have to’ make some rhubarb sauce – due to my annual robust rhubarb harvest – I wanted to think of a way to use another type of sweetener – and make a sugar-free rhubarb sauce.

Even me, a person who does not really have a sweet tooth, cannot handle eating rhubarb sauce without a sweetener. There are a few fruits where sweetening is mandatory – rhubarb and cranberries as a couple of examples.

You can see by the recipe title that there are some strawberries in this sauce. The strawberries, however, are not the sweetener. While obviously sweeter than rhubarb, they are still not sweet enough to counter the tartness of rhubarb. They are, however, an important ingredient in this sauce for a couple of reasons.

While we tend to think of rhubarb stalks as quite red in color, there are actually a lot of green stalks as well as green and red blend rhubarb stalks. As such, when they are boiled down, the color becomes a little less – or should I say a lot less – appealing. Adding strawberries to this sauce helps to add a little more red color – naturally, of course.

My mother used to add strawberry jello powder for both the addition of the red color and for the setting properties of the gelatin. I am not a fan of what is in jello powder – lots of refined sugar. I will suffer through the less-red color and saucier texture by using just strawberries.

As I mentioned, I wanted to use or find a different sweetener for this rhubarb sauce. When it comes to natural or unrefined sweeteners, there aren’t that many available…so, my choices were limited by virtue of availability. (It makes it easier to decide when I don’t have a lot of options – well, sometimes :-).

In my pantry and / or fridge…my options were honey or maple syrup – and I mean, real maple syrup – not that sugary maple flavored stuff that kids tend to love.

So, maple syrup it was! I could have used either honey or maple syrup but, I had a lot of maple syrup so…that was an easy decision. I have to admit I also thought the flavors of rhubarb and maple syrup would blend nicely….and they do!

And now for the complete and super easy recipe.

    With a new batch of freshly picked rhubarb, I made this just the other day and I did not have any strawberries. So…I found some frozen cranberries in my freezer and gave that a try. I added about 1/2 cup.
    The cranberries added to the color – making it more red, and ultimately more appealing.
    However, they did not add any sweetness (maybe that was obvious). In fact, they did the opposite. So you may want to add more maple syrup.
    Another point to make about adding cranberries…because of their texture and hearty peel, they do not fully break down so you do get some chunks of cranberry peel in the rhubarb sauce. If that bothers you, don’t substitute cranberries and stick with the strawberries.
    Have a Happy and Yummy Rhubarb Season!
