If you happen to have taste buds that are similar to mine, you will jump for joy at the flavor that rhubarb brings to the palate. It’s so hard to describe the tart, wonderful flavor that is loved by so many Brits.

What’s the Best way to Prepare Rhubarb?

While it’s subjective, this rhubarb sauce is, without a doubt, one of the best ways to prepare this amazing vegetable (yes, it’s a vegetable, not a fruit). One of the ways I use this wonderful pink sauce is to top my lemon posset, and other similar desserts, like panna cotta, and rhubarb fool.

Never heard of posset? Then let me introduce you to another fabulous creation: this lemon posset recipe is courtesy of my pal, Cynthia, from What a Girl Eats.

Of course, you can keep it even more simple, and just serve it over vanilla ice cream, which is also a superb dessert idea. If you’re already a massive rhubarb fan, then head over to my collection of rhubarb recipes, to which I have just added rhubarb applesauce!

What is Rhubarb Sauce Made of?

cooking rhubarb sauce — Believe it or not, no water was added.

Rhubarb sauce is made of only two ingredients: rhubarb and sugar. According to Wikipedia, rhubarb is 97% water, so there’s really no need to add water.

Can you Sweeten Rhubarb Without Sugar?

Of course you can sweeten rhubarb without using sugar, but in doing so, you will also change the flavor. For example, adding other sweeter fruits, like strawberries or peaches will add some sweetness, but you’ll also have the flavor of the other fruit, and will still need to add sugar, honey or other sweetener.

A recent idea is to add dates to sweeten rhubarb. While dates are naturally very sweet, I personally didn’t like the combination’s flavor and texture.

Can You Eat Rhubarb Raw?

Many people have asked me this question, so I’m adding it to my rhubarb posts. Yes, raw rhubarb is not only edible, but delicious! You’ll have to have a sweetener as it’s so sour, but this is how children in Scotland are introduced to eating rhubarb raw. Give it a try!

What Can I Use Rhubarb Sauce For?

As a topping for posset, panna cotta, cheesecakes, ice cream, and crème fraîche.

In overnight oats, with oatmeal/porridge.
As a side sauce (like applesauce) with pork, lamb or other meats.
To flavor your yogurt, labne or smoothie bowls.

Added to parfaits, smoothies, and rhubarb fool.

In cakes and baked goods. I’ve added a dollop to the center of these rhubarb muffins before baking them. Incredible!

And if you noticed what you probably thought were rose petals, you are mistaken. These “petals” are actually dehydrated rhubarb chips!
