Reference information

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.

Recipe notes

You’ll need about 1 ¼ kg / 2.5 lbs or a bit more unpeeled onion to start.
Pack onion slices relatively tight into the jar.
The vinegar can be barely enough. Be prepared to heat 50% more in a microwave at the last minute for top up. Mind surge effect when removing from microwave.
