Bill..when i first found ETS some years ago i sort of went "survival crazy",in a nice way.no basement full of stuff but i did look around the web for gear that might come in handy if a canoe trip went bad.before ETS it was just a few things in a PFD and what in the world was a PLB and they cost what!!
so anyway i found a supplier who sold edible candles.
"shave some on toast" was the lead on the sales blurb.
so i got a few.made from the oils found in olives and other foods rather than petro oils you should be able to eat one in a pinch.what got me into the "eat your candles" idea was reading some old,pre WW1,accounts of British hikers and climbers doing that when they were lost or snowbound.maybe back then tallow candles were still available.
