This Sweet Onion Relish is from the wonderful So Easy to Preserve put out by the University of Georgia.
The recipe calls for Vidalia Onions, the pride of Georgia, so if you have access to a lot of them cheaply where you are, you may want to use those.
For this photo session, we used sweet red onions as there was a bumper crop of them at the time that needed using up.
This is a recipe that you can make in the winter if you see large bags of onions go on sale and the canning bug bites you.
We also cut the recipe in half.

How to water bath process.
How to steam can.
When water-bath canning or steam canning, you must adjust the processing time for your altitude.
For salt substitute, Herbamare Sodium-Free was used as it is non-bitter and non-clouding.
For stevia, Better Stevia liquid stevia was the stevia used as it is non-bitter, easy to use, doesn’t increase density and impacts neither pH nor nutrition.
Australia and New Zealand vinegar strength special notes.
- You’ll want to start with about 2 1/2 to 3 kg (6 to 7 lbs) of onions before prep.
- Vidalia Onion is not a specific variety of onion (legally, 24 different varieties of onions can be sold as Vidalias). It’s a marketing term applied to sweet onions grown in 20 counties of south-east Georgia which have the right soil to produce sweeter onions. If you are in Washington State, or Oregon, you might wish to try your local Walla Walla onions.
- “Grinding an onion” might seem like a curious operation to perform. What they mean is they passed it through a meat grinder attachment such as the one shown below. “For recipe development, vegetables were ground using a coarse blade stand mixer attachment.”1
