Peel and chop kiwis, and place them in a deep saucepan with sugar and citrus juice. Jam bubbles during cooking, be sure you have enough headspace to avoid overflows.
Cook the kiwi jam for about 10-15 minutes, until it reaches gel stage. Test for it on a plate placed in the freezer, or with a kitchen thermometer (220 degrees F).
Ladle the finished kiwi jam into jars, leaving a small 1/4 inch headspace. De-bubble the jars, adjust headspace and then cap with 2 part lids.
For a fridge or freezer jam, allow the jars to cool completely before storing in the refrigerator or freezer.
If canning, process in a water bath canner for 5 minutes, then turn off the heat and leave the jars in the water for an additional 5 minutes before removing them to cool. Store any unsealed jars in the refrigerator, and place the sealed jars in the pantry. Sealed jars should last 12-18 months without losing quality.
Notes
This kiwi jam recipe can be made as a freezer jam or as a recipe for canning. If storing in the freezer, be sure to use straight-sided freezer approved jars. If canning, use only canning approved jars and be sure that you're familiar with the basics of water bath canning.
