What? A rhubarb relish! I love BBQ baby back ribs, and I thought this relish would be a great addition to the meal! So, I bought the ribs for dinner and asked the family to try this relish, and they all loved the sweet-tart taste. The addition of raisins did the trick. This relish can be used many different ways, which I listed below. Pair it with cheese, pasta, pork, chicken, or any grain salad. Rhubarb can be found locally now in many supermarkets today. But, the season is short, so don’t wait to buy when you see! You may also be interested in my Rhubarb Tart made with Phyllo on my blog.

How to Use the Relish:

  • Add the relish in a bowl and add to your cheese board.
  • Place on a party table as a condiment for your appetizers.
  • Slather on hot dogs or perfect for your bratwurst.
  • Spice up salads, grain dishes or bowls.
  • Spruce up your gourmet sandwiches.
  • Perk up pork your tenderloin as a topping.
  • Kick up vegetarian meals
  • Dress up your dips by adding them as a finished touch.


The supermarket and farmer’s market will sell you these long stalks, once home they need to be washed and trimmed.

Another option is ordering from Melissa’s Produce in this handy precut package.

Always try and start with everything measured out, which makes your cooking time easier and more enjoyable. Called Mise en Place, a cooking term for everything in place.

Sliced as you would slice celery.

Cook until softened and as a thick sauce.

Check to see if it has thickened, this needs more time.

Enjoy this recipe,
