Method
Simmer rhubarb with vanilla
- Combine fresh rhubarb, water, and vanilla bean (pod and seeds) in a large pot and simmer for 15 minutes, until the mixture looks rosy and fragrant.
- Strain the mixture through cheesecloth or a fine mesh strainer, pressing to extract all liquid (about 3 1/2 cups total) and pour the strained juice back into the pot.
Boil and set with pectin
- Stir powdered pectin and lemon juice into the rhubarb juice, then bring the mixture to a rolling boil.
- Add sugar all at once, then return to a hard boil and boil for 1 minute while stirring constantly.
- Remove from heat, skim off any foam, and remove the vanilla bean pod.
Jar and process
- Ladle the hot jelly into sterilized jars, leaving 1/4-inch headspace, and wipe jar rims clean.
- Process the jars in a boiling water bath for 10 minutes so they seal properly.
- Let jars sit undisturbed for 24 hours to set completely, until the jelly is ruby-pink and translucent in the jar.
Notes
Pro tip: Keep stirring during the 1-minute hard boil to prevent scorching and ensure an even set. Store sealed jars in a cool, dark place for up to 12 months; refrigerate after opening and use within 3–4 weeks. Freezing isn’t recommended for best texture after canning, but you can freeze unopened jelly in freezer-safe containers for up to 3 months. For a lower-sugar swap, use a low/ no-sugar pectin option and follow its label directions for timing and ratios.
