Olive you so much...
It is the time of year that many people cure their own olives. There are
several ways to cure olives—each producing olives with unique flavors. A
common way uses a solution of lye to prepare the olives.
The lye used to cure olives must be 100% pure sodium hydroxide (NaOH) –
also commonly known as caustic soda or lye. Pure lye is available in
some hardware stores and farm supply stores or can be ordered from some
chemical suppliers or soap making suppliers. Because lye is a reactive
chemical it is shipped in small quantities and often only by surface
transportation. You can search the internet for lye sources in your area
under “soap making supplies” or “sodium hydroxide.”
