How to Make Sweet Onion Jelly
- Puree 1 large sweet onion (about 1 cup chopped) and 1/2 cup apple cider vinegar in a blender until completely smooth.
- Pour the onion-vinegar mixture into a medium-sized saucepan.
- Add 2 cups granulated sugar and 1/4 teaspoon crushed red pepper flakes. Bring to a rolling boil over medium-high heat, stirring constantly.
- Boil for 5 minutes, then reduce heat to medium. Stir in 1 package (1 3/4 oz) powdered pectin.
- Increase heat to high and bring to a full rolling boil that cannot be stirred down. Boil hard for exactly 1 minute, stirring constantly.
- Remove from heat and skim off any foam. Carefully ladle the hot jelly into hot, sterilized jars, leaving 1/4 inch headspace. Wipe jar rims clean, place lids and bands on jars, and tighten fingertip-tight.
- (Optional) Process in a boiling water bath for 10 minutes (adjust processing time based on your altitude – consult a canning guide for specifics). Let cool completely. Lids should seal with a satisfying pop. If not, refrigerate and use within a week.
- If not canning, allow to cool completely in the saucepan before transferring to an airtight container. Refrigerate and use within 2-3 weeks.
