Ingredients Method Notes

Ingredients
  

  • 4 cups rhubarb chopped
  • 2 cups granulated sugar
  • 2 tablespoons lemon juice
  • 1 teaspoon lemon zest optional
  • 1/2 cup water

Method
 

  1. Wash, trim, and chop rhubarb into small even pieces for faster and more even cooking.
  2. Add rhubarb, water, and lemon juice to a pot. Cook over medium heat until the fruit begins to soften.
  3. Simmer for 10 to 15 minutes until rhubarb breaks down and becomes mushy.
  4. Stir in sugar slowly until fully dissolved into the fruit mixture.
  5. Cook uncovered, stirring often, until the jam thickens and becomes glossy.
  6. Check thickness using a cold plate test. Continue cooking if needed.
  7. Remove from heat, cool slightly, and transfer into clean jars. Seal and store.

Notes

  • Fresh rhubarb provides the best flavor and texture, but thawed frozen rhubarb can also be used successfully.
  • The cooking time may vary depending on the moisture content of the rhubarb. Continue simmering until the jam reaches your desired thickness.
  • If you prefer a smoother jam, use a potato masher to break down the fruit during cooking.
  • For a chunkier texture, leave some larger pieces of rhubarb intact while simmering.
  • The jam will continue to thicken slightly as it cools.
  • To test if the jam is ready, place a spoonful on a chilled plate and let it sit for 1 minute. If it wrinkles when pushed gently, it is ready.
  • Stir frequently during the final stages of cooking to prevent scorching or sticking to the bottom of the pot.
  • Adding lemon juice helps balance the sweetness and supports proper thickening.
  • For extra flavor, stir in a small amount of vanilla extract, orange zest, or fresh grated ginger near the end of cooking.
  • Store the cooled jam in clean, airtight jars in the refrigerator for up to 3 weeks.
  • For longer storage, process the filled jars using approved water bath canning methods.
  • Do not overcook the jam, as it can become too thick once cooled.
  • If the jam becomes too thick, stir in a small amount of warm water before serving.
  • This recipe is easy to double for larger batches, but allow extra cooking time for the jam to thicken properly.
  • Rhubarb leaves should never be used in cooking and should be discarded before preparing the recipe.
