Cooking Tips: Cooking oils

Cooking oils--like corn, sunflower, or peanut--can deteriorate, or turn rancid, faster in the warm summer months. Rancid oils have an unpleasant paint-like aroma, and the container often feels "tacky."  Once an oil has become rancid, there is nothing to do but discard it. Consider refrigerating your oils during the summer for better shelf life.--FN Calendar
