Olive oil is made by pressing with a machine called an expeller. You can buy them but they are expensive. The mash left over from the pressings is called pomace. Pomace oil is hexane-extracted. Probably none of this is practical for the home unless you are a DIY fanatic with lots of time and money.





Olives are process for eating by curing in a lye solution. I've never done this although I know one or two people who do. You have to know what you're doing so you don't poison yourself.
