Ingredients

  • 2 cups fresh rhubarb, sliced into 1/4-inch pieces – Look for rhubarb with vibrant red stalks; they’ll give you the best color and flavor.
  • 1/2 cup white vinegar (or apple cider vinegar) – White vinegar gives a cleaner taste, while apple cider vinegar adds a subtle fruity note. I prefer white for this recipe.
  • 1/2 cup water – Helps to dilute the vinegar and create a balanced brine.
  • 1/4 cup sugar – Balances the tartness of the rhubarb and the heat of the spices.
  • 1 teaspoon kosher salt – Essential for preserving and adding depth of flavor.
  • 1 teaspoon red pepper flakes – Provides a delightful kick! Adjust to your spice preference.
  • 1 teaspoon mustard seeds – Adds a nice pop of texture and a slightly earthy flavor.
  • 4–6 black peppercorns – Enhances the overall spiciness.
  • 2 cloves garlic, sliced – Garlic adds a savory depth that complements the rhubarb beautifully.
  • 1–2 slices fresh jalapeño or a pinch of cayenne pepper (optional) – For those who like things extra fiery!

How to Make It

  1. Wash and trim your rhubarb; cut into 1/4-inch pieces. This ensures even pickling. I like to use a sharp knife for clean cuts.
  2. In a saucepan, combine vinegar, water, sugar, salt, red pepper flakes, mustard seeds, peppercorns, garlic, and jalapeño (if using). Bring to a boil, stirring until sugar and salt dissolve completely. This is the most important step to ensure proper preservation.
  3. Pack the rhubarb tightly into a clean pint-sized jar. The tighter you pack it, the less air will be trapped.
  4. Pour the hot brine over the rhubarb, making sure all pieces are fully submerged. Use a spoon or chopstick to gently press down and release any air pockets. This prevents spoilage.
  5. Cool to room temperature, seal the jar tightly, and refrigerate for at least 24 hours. For the best flavor, I recommend waiting 3 days before enjoying.

Substitutions & Additions

Feel free to experiment! You can substitute brown sugar for a deeper molasses flavor, or try different chili flakes for varied levels of heat. Adding a few sprigs of fresh thyme or rosemary can create a more herbaceous profile. A bay leaf is also a nice addition.

Tips for Success

  • Use clean jars: Sterilize your jars to avoid spoilage. I usually wash them in hot, soapy water and rinse thoroughly.
  • Pack tightly: Leave as little airspace as possible for optimal preservation.
  • Don’t overcook the brine: Once the sugar and salt are dissolved, you’re good to go! Overcooking can affect the flavor.
  • Prep ahead: You can prepare the brine ahead of time and store it separately in the fridge. Just combine it with the rhubarb right before serving.

How to Store It

Store your spicy pickled rhubarb in the refrigerator for up to 2-3 weeks. They’ll be at their peak flavor around day 3, but will stay tasty for a good while afterward.

FAQs

  • Can I use frozen rhubarb? While fresh rhubarb is best, you can use frozen, but be sure to thaw it completely and drain excess moisture before pickling.
  • What can I use pickled rhubarb for? It’s amazing on cheese boards, with grilled meats, in salads, or even as a unique condiment for tacos! Get creative!
  • How spicy is it? The spiciness is adjustable. Start with one teaspoon of red pepper flakes and add more according to your spice tolerance.
  • Can I can this recipe? While this recipe is designed for refrigerator pickling, it can be adapted for water bath canning. Make sure to follow proper canning procedures to ensure safety.
