Thanks for the article, I tried to cure olives once many years ago. But olive tree isn’t doing much these days, unlike in the past.
This is point about food grade lye is interesting.
But Hank, shouldn’t you use “food grade” lye? Well, after much research, I can find no hard evidence—none—that says there is any difference between so-called “food grade” lye and non-food grade lye. So, you can order the food grade stuff through that link above, or go to the hardware store and use a 100-percent sodium hydroxide drain cleaner. Both will work.
