Rhubarb Nutritional Information

Rhubarb is a tart fruit and is usually eaten in recipes with a lot of sugar, so low-carbers should be wary of any rhubarb-containing dishes made for them.  On the other hand, the rhubarb itself contains very little natural sugar, so it's a great choice if you can control the amount of sugar in the food.

In my youth, it was popular to nibble on the raw stalks of rhubarb (which seemed to grow everywhere) with sprinkles of salt.

I have heard that doing the same thing with sugar is common in other places. (Don't eat the leaves, though, as they are poisonous.)

Other Serving Suggestions

Stewed Rhubarb: Just cook diced rhubarb with a little water.  Add a little cinaomon or nutmeg if desired.  When it is soft, sweeten to taste with your favorite sugar substitute.  Serve with sugar-free whipped cream.

Pickled Rhubarb: Make as you would other types of pickles, such as watermelon rind pickles, making a tart condiment.

As a Vegetable: If you are making a rich, heavy dish, adding a little cooked minced rhubarb can add a spark.
