Pretty much the same criteria I use Bridges. Plus a couple more for us: the glass bottles should be a dark colour to keep out the light, with a sealed cap to make sure it hasn't been opened. It must pass the sniff test when I get home and open it, no 'rancid' smell. And it must taste good if it has any taste.
Ive only ever returned one bottle, because it was rancid, and the supermarket changed it for another which was fine. I buy cold pressed, Extra Virgin.
We use it instead of butter on potatoes, slow cooked leg of lamb, baking, salad dressings, marinades.
On toasted sandwiches in the s/wich maker. Stir fry veg. We go thru a 500ml bottle about every 2-3 weeks for just the 2 of us.
I read somewhere it shouldn't be burned, like when searing steak or roasting meat in the oven, dont know if that's correct. Hasn't killed us yet and I've used it for many years.

Agreed. Kate had no obligation to release that photo, adjusted or not and the media has no right to criticize her for allowing it to be published. An unaltered photo by paparazzi's of her and the children would have been bought for a large sum of money and would not have been criticized for out of focus or even blurry subjects due to camera movement. Yet, she voluntarily provides a nice photo of her and her children, the media goes crazy over some minor adjustments.

The media needs to get an update on reality.
