Post-carbon food preservation

The solar box cooker "SOS sport" is preheated to 250F/120c and is ready to can fruit. I just placed some tomatoes in here to see how well they seal up. It should take about 2 hours to bring the fruit to boiling inside the jars. I cored and quartered these and didn't bother with the skins.

You can make a solar cooker yourself or buy one, they're fun to use. Because I'm not boiling any water indoors, it stays nice and cool in the house.

This process is all detailed in Eleanor Shimeall's book "Eleanor's Solar Cookbook" details it all. Her book can be ordered by writing her at PO Box 1022, Borrego Springs, CA 92004 USA.
