On the Home Cooking Board I saw that Costco's Kirkland's 1st Cold Press EVOO was recommended. Went to the local Costco and of course the quantity was huge. There are just the two of us and the ministry to the sick is not that large. I understand the principle of sharing. I do have several questions. (1) Will Olive Oil go bad? (2) Will refrigerating or freezing lengthen shelf life? (3) Are their other ways to extend shelf life? We did not purchase. Wife was at Wal-Mart and purchased Pompeian First Cold Press EVOO so I will need info for next time when this purchase runs out. Who would have thought, buying oil during Hanukkah!
