Better than Bleach: Use Calcium Hypochlorite to Disinfect Water
EPA instructions for preparing calcium hypoclorite solution for disinfecting water.

Note...calcium hypoclorite is very corrosive. Read up on the care and storage of this stuff...a sealed glass container might be the best. If the container is not leak-proof...the fumes will rust nearby metal objects.
Kart, I have recipes I collected for easy bread making on the top of a stove (thinking one wouldn't have a working oven) and other easy recipes for desserts (like cobblers) on top of the stove and other easy meals to make on top of stove. Most of these recipes came from my researching old Indian recipes and early settler recipes. None are complicated as the idea was EASY and using ingredients one would have on hand in a prepper mode.
None require any ingredient that would be in a fridge since we wouldn't have a fridge. Indians and early settlers didn't have a fridge or oven.
I have thought of asking you if I could post some of these recipes when you put on a prepper thread. If that is okay with you, I will do it but right now I'm in Ohio in a hotel with my travel computer and the recipes are not on this little computer. I should be home by Sept. 12 and could start posting those around that time.
Let me know if I can do that.
As to your posting prepper threads, normalcy bias causes some people to deny anything could happen and prepper posts make them uncomfortable so some complain. Ignore those coplaints as you help many people and those are the ones you reach with the threads.
