BUYING IT
The most important thing to remember when buying EXTRA VIRGIN olive oil is that fresh is best. Look for the date of production.
Remember PURE just means it's not mixed with other vegetable oils. It's usually industrially produced. Don't think about buying it.
LITE is the biggest con of all. There are not less kilojules in LITE. It's processed and tasteless.
POMACE is what is made out of the leftover mush from extra virgin production. When I first saw this made in Spain I couldn't believe it met food quality standards. Imagine black muck, put through an industrial process to convert it to an oil, add a bit of green and you have pomace oil.
