Again, good information. I guess I was assuming alcohol would be top of most people's list and Yeast is certainly something you would want to "create". I was thinking of chemical leavening, but maybe that's not necessary. And I should have included Alcohol on the list as it is a disinfectant, fuel, etc.

I don't think I'm going to sue any plants ;-) but yes a nice horticultural setup seems to be an important part of LTS - heirloom seeds, medicinal plants such as aloe, hardwood timber, and of course fruits and veggies all seem important. Substitution is fine and in fact, I'm keen on identifying safe substitutes to any products. Recipes are important because it's very easy to hurt yourself processing some of these things. And in a true SHTF TEOTWAWKI situation, getting non-renewable raw resources is going to be very difficult depending on your locale and ability to salvage.

I know in my area that I can find some coal and of course there's plenty of farmland and timber. Others may have ready access to salt and other mined materials, so even identifying where/how to find those seem like valuable information. Maybe even basic metallurgical skills such as smelting and forging should be included on this?
