My local Kiwanis Club was selling Vidalia onions as a fundraiser this spring and I bought a 25 pound bag. So, I decided to make relish. This recipe uses white vinegar and has only a few, simple ingredients.
If you can't get Vidalia onions, any sweet onion will do just as well.
Step 1: Getting the Jars and Lids Ready
First, I washed my pint canning jars in the dish washer and kept them hot until I was ready for them. I simmered my lids and rings in hot water and kept them hot as well.
Step 2: Making the Relish
I chopped 10 cups of onions.
I combined my onions in a non-reactive pan, along with
2-1/4 cups white vinegar
1 cup sugar
2 Tablespoons celery seed
2 teaspoons canning/pickling salt
I stirred all the ingredients together and brought the mixture to a boil, reduced the heat and simmered for 10 minutes.
Step 3: Filling the Jars
Ladled the mixture into the hot pint jars leaving about a half inch of headspace ( you can use a measuring tool). wipe the jar rims with a damp cloth and, using a magnetic wand, remove the lids and rims from the hot water, tightening them to a fingertip tightness on the jars.
Step 4: Processing Jars
Process the jars in a boiling water bath for 10 minutes, then removed the jars from the boiling water using a jar lifter.
Step 5: Finishing Up
Set the jars on a folded dish towel on the counter to cool make sure to listen for the PING of each successfully sealed jar.
