Tips & Variations
- Use the cold plate test by chilling a small plate beforehand; if the jam wrinkles when pushed, it is ready.
- For a spiced twist, add cinnamon or ginger during cooking.
- If you prefer a chunkier jam, reduce cooking time slightly before adding sugar-pectin mixture.
- Ensure jars and lids are properly sterilized to avoid spoilage.
Storage
Store sealed jars of rhubarb jam in a cool, dark place for up to one year. Once opened, keep the jam refrigerated and use within 3 weeks. To reheat, gently warm jam on the stove or in the microwave for easier spreading.

FAQs
Can I use fresh lemon juice instead of bottled?
Yes, fresh lemon juice works well and adds a bright citrus flavor. Use the same amount as called for in the recipe.
What if my jam does not set properly?

- 4 cups granulated sugar
- 1/2 cup water
- 1/4 cup lemon juice

Instructions
- Prepare Rhubarb: Wash and trim rhubarb stalks, removing any leaves and root ends. Chop the rhubarb into 1/2-inch pieces until you have 4 cups.
