Is there anything worse than rancid olive oil? It smells bad. It tastes bad. It's just bad. And it goes bad faster in the heat of a kitchen, in the heat of summer. That's why we buy ours in a tin can and not in a clear plastic bottle. Clear bottles allow light in, making the oil go bad more quickly. Also, buying the larger container saves us money, and we tend to use olive oil quite a bit. However, if you aren't a bulk-shopper, another way to solve your oil storage problem would be to buy a pretty oil can like the one shown here: http://www.foodbuzz.com/daily_special. Isn't that schmancy? Save your money by saving your olive oil. Go tin!
