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 need about 1 1/4 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.
